I honestly never had trouble with drones or the wireless matrix. I was able to do some really cool stuff with Drones, like when I made my AI Street Samurai, since they were easy to mod into what you wanted. But then, I came to Shadowrun from D&D 3.5 and HERO 4th/5th, so maybe I was used to more complexity? I guess I can see how they would be difficult for someone coming from M&M or one of the rules-lite systems like the Window. But once you learned them, I never had trouble doing what I needed to do as a hacker or rigger.
I will admit that 'single-class' hackers went away for the most part in 4e. But other than... well, pretty much other than Sammmies who did nothing but shoot and bash stuff everyone was more hybridized. That's not a bad thing. In a group of 5, where you need to cover Matrix, Magic, Guns, Talking, Covert Ops, and Transport, having people who had a primary and a secondary role was a good thing. This gave you redundancy, so if the party got split, or the specialist got tagged, then you weren't completely hosed for the rest of the run. With 5e forcing riggers and hackers to not only be 'single-class', but not being able to hang back in safety, your whole group can get fucked in a hurry if someone scores a lucky hit on the decker, for instance.
Hacking was viable before, especially if you sidelined in rigging. Even the trope of hacking the corpsec's eyes was possible, though only in the case of those who linked their eyes to their PAN for tactical reasons, or for some stupid reason left the wireless on. But a hacker not being good in the meat world wasn't a problem, because they were usually on Overwatch, editing camera and sensor feeds, opening doors, silencing alarms, and so on, from the safety of the van or other secure area. That's like complaining that the Bard in D&D doesn't hit like a Barbarian or sling fireballs like the Wizard. But 5E kicked that in the balls, and then decided to fuck with everyone else with wireless bonuses so that hackers didn't feel like they got shat on specifically (that 'honor' was reserved for TMs). It was a case of fixing things that weren't broken, and fucking it up worse than before. Which explains most of what you need to know about the 5e matrix. Like the old programmer's joke about having 36 bugs to fix, so you patch one, and now have 87 bugs to fix.
5th is a work in progress, yes. But they should have held off on 5th until they defucked things, instead of going whole hog on the wonderful 'Year of Shadowrun' that fizzled into utter crap. Things like limits add additional complexity where things were already fucked up enough (I give you alchemy, folks), there are parts that are demonstrably worse than their 4e versions (weapon and vehicle mods, to say nothing about the lack of spell creation rules), there are sacred cows that should have been sent to the butcher a long time ago (Priority generation and scaling Karma costs to advance), and there are areas of the game that need a ground up rewrite instead of a Data Trails patch job (TMs).
