As a professional Pink-Mohawk Player (read my tag line if you don't believe me). My gaming group loved heavy armor (aka lots of dice), big weapons, and lots of explosives (read 2 mages). But we also like our games deadly, so we were almost always moments away from burning Edge. Luckily, we had amazing rolls so that never happened.
My point is, while bikini/muscle shirt tops look cool in art, it makes no since in a shoot out. Why are your players using armored clothing when Armored Jackets/Executive Business level of armor exists? I get occasionally you cant use those, but there are plenty of armor ~9 high end clothing/specialty armor out there for the players (and bad guys) to use.
As for 6ed armor thing, I get that the damage codes and soak pools got stupid fast, Troll with Nodachi anyone, same Troll with all the stackable armor were? But, armor only giving a single die reroll effectively, unless you have more edge to use, is crazy as well. Honestly, to me the fact that people are already saying how they would modify the rules for home games scares me. That is showing, to me, that something doesn't work or at least is a bad selling point.
Finally, yeah 5th was horrible for a lot of rules and others were useable, with either clarification, officially or via table calls. But I personally love crunchy games. The trend of simplify everything is personally a copy of D&D5 ability to reclaim top dog of RPGs, held for a decent while by Paizo and Pathfinder 1 (also super crunchy). Now, suddenly, both Pathfinder and ShadowRun are like, yeah lets do that! Granted both systems needed work, but not, in my opinion, how it was done.
