Aye, its understandable a lot of people are annoyed at the whole skin link thing. Mostly because its so big a thing to form the direct connection, and you know there will be an augment for it too.
I agree that whole Mathmatical thing should have been something else.. Unless you know, there was some technomancer stuff to work with it. Like a technomancer fighting style that uses mathmatics. But I have to ask.. Why in the world does not a single Echo expand with submersion grade? Why is it so often nothing more than a small stat increase?
Also, I want to note that I believe you can put an agent on a commlink now. Could be useful.
Understand that i cannot go back and rewrite the core mechanics of TMs. What they are is what we have to work with. I didn't write the complex forms or echoes in Data Trails so i'm in the same boat as you.
Skinlink was an echo in 4E and it's an echo in 5E. It's done and i can't go back and change it, so asking for it over and over again will not make that happen.
MMRI will obviously need to be fixed because it's a reprint. I don't know if the writer just didn't know that was already an echo or if something got jacked in editing. I'll ask him about that and Mathemagics (because i have no idea what it's supposed to be for either).
As far as echoes not being tied to Submergence grade, i don't know why that has been the case so far, but i have several planned that will be tied to submergence grade.
I am considering something similar to sidebar in Unwired that contained the "alternate" technomancer rule. That gets secondary priority though. I am looking to address the Fading issue and bring back/update some of the more interesting echoes from 4E.
Streams and Paragons are also top of the list priority. It ain't right that every character has to be a techno-adept.
Oh of course. Its never really just a call for you to go and fix all our woes, but rather whoever would be actually the one who would be involved in actually changing and erratting stuff.
Which makes me think, possibly a reason why Errata seems to be so slow for the somethings. Could it be because of some sort of legal mumbo jumbo stuff that is really out of both the freelancers and catalysts control but is stuck somewhere in the Organization of governmental bureaucracy organization of red tape? I've heard some horror stories before about companies being forced by some governmental groups to sue the fans in order to keep a hold of their licenses because the fan was making stuff for the game for free, and the government figured if you're letting this one person do it, everyone should have your thing now.
I'm still in the boat that Mathemagics could be great if it had things to go with it, that allowed a Technomancer to kill people with their brain. I know Encryption and Decryption are somethings that were in 4th as some sort of program thingies now. But looking at it from a non-4e mechanics view.. Mathematics is pretty big in creating ciphers. Alan Turning for example broke the enigma with his extensive knowledge of math. So cause I wasn't looking at it through the definition of encryption/decryption as being 4e related actions, I saw it more as being something tied a little more to Analytical mind.
Which reminded me of two things.
Gun Kata and A scene in firefly where River Song mumbles out some mathematical equations to taking out her foes. This leads to me thinking of somehow getting a new defense quality, like acrobatic defender, but for something Mathematical. Or other ways of using a fighting style based around calculating numbers.
I dunno though, I can't really get too far in it myself.
