Not get a direct connection from within a host, only from physical connection, mean that you no longer can interact with devices out on the grid from within a host. Also you will screw over TMs that by RAW can't establish a physical connection. This would be a bad idea (tm).
Not give you a direct connection from within a host mean that you can't interact with the device (whose icon is located out on the grid). Also, forcing a physical connection in order to bypass host ratings mean that a technomancer have to fight host ratings for every single slaved device they want to control. From a balance perspective this is not even an option. You need to let go of that house rule....
To be honest, I don't know the Technomancer rules (no one I play with has, or is vaguely interested in them, so I never bothered). I naturally assumed they *could* direct connect to something without a cable. But, that small change is all that's necessary to balance that part. Frankly, it's weird that they can't.
Regarding "interacting to devices from within a host", as I've stated, this is not RAW. This is something you learned from someone related to the authoring. But it if wasn't for that piece of knowledge, nothing I've ever read suggests devices can't be in a host, or seen or connected to from within it. RAW wouldn't even need to change to solve this problem, just the interpretation of them.
So, to solve your problems, we need a single change for TMs that should already be there. I'm cool with that. Why wouldn't anyone else be?
What rule change? Seem to have overlooked it or maybe it isn't really clear to me what you mean.
Oh, just the whole "Don't give out direct connections for a single mark on the Host". Whether it requires two marks, or my personal opinion that it should require some physical connection somewhere in the WAN to fool the WAN into thinking you're a part of it. The latter would bring about interesting gameplay.
One of the biggest complaints in the past was "Hey, I am gonna go out and get food, while you run that matrix bit" and SR5 has done very well to fix that. Slug, your houserule that you mention seems like it will just take a step backwards, back towards that time when hacking was so slow, it needed to be done separately from the group. OR, so slow (needing extra marks, extra connections) that it can't be done alongside the runners, because they will be moving faster than their hacker can hack.
How so? Yes, if you need two marks on the Host, I guess that technically takes more time, but not *that* much more. And using my rule of "You need to be connected to the WAN" forces either the hacker to direct connect (which most will already do to bypass Host ratings) or fight the Host ratings a little bit more (either two marks on the Host instead of one, or entering the host (1 mark) and marking a device w/o a direct connection (1 mark). None of this slows the hacker down so much that he's playing a separate mini-game, nor slows him/her down so much he/she can't keep up with the rest of the group.
A street level campaign's hacker would certainly be a bit tougher, but that's kind of where I'm going with this.
I really don't understand where there can ever be a consequence-free Hack on the Fly.
If outside of the Host, very little can be done to you if you fail HotF. You get a "mark", but that's useless to anyone but the Host spider, who is very likely not going to stop defending the Host just to come look for the "script kiddie" who just failed to enter the Host (if you can't even get inside, what kind of threat could you possibly be?). And you don't get GOD on you unless you *really* failed that HotF trying to get into a *really* high level host. Which is why it's nearly consequence-free.
Even counting your average schlub with a commlink.. your average guy on the street (Thugs and mouth breathers) don't have a point of edge to try using their commlink to hack. You next step up, Gangers & Street Scum typically have 1 edge point between the group.. still not enough to reliably try hacking with a commlink.
That example is operating under the assumption that we're talking about a person, not a "group" whose edge is combined purely for the ease of play.
Since decks are illegal, most common Hosts don't have to worry about people with Decks showing up.
Do they? yeah. Just like in the real world. Guns are illegal, most convenience stores are uber-protected because of the chance someone might show up with a gun and rob them. It happens, and sometimes they take extra steps, but usually, the robber robs them and gets away. Until recordings are turned over, and the police get involved.
Decks aren't illegal, just restricted. Second, clearly they do worry or they wouldn't prepare. Also, guns aren't illegal, at least not in the US. In fact, the fact that many convenience stores protect themselves from robbery by gun point is because of just how common guns are. Go to a small convenience store in a small town, and even late at night, there's not a lot of precaution. Go to a worse area, and you're talking to someone behind thick plastic. People don't pay for protection they are very unlikely to ever need.
I'll say again that the presence of Spiders and IC proves hacking isn't that rare. And remember, even if decks were strictly F(orbidden), a little tech savvy and a little Matrix searching and you could build (code?) one. We'll likely be getting rules for that in a later source book (people always find ways to hobble together something if it saves them huge costs).
But, if that really concerns you, then simply implement this. When you get a legal mark on a Host because it invited you, it sticks a mark on you. if you remove that mark, you are immediately kicked from the Host. So, non-criminal people in Hosts, that aren't trying to do criminal actions, don't have to worry, and if you have criminal intent, then you are that much easier to track, unless you acquired your mark illegally.
This is actually a really good idea. It doesn't go that far in dealing with what I wanted to deal with, but it's at least a good idea for the seemingly silliness of Hosts inviting marks despite the security hole. Thanks for this.
