@SeanJP the +2 feat if picked stops you from getting a feat, you can call it whatever you want but it still is in the feat section. I guess you can consider this a minor jab at 5e but really its whatever.
I havent played it, but I read through the rulebooks, and most of the things I objected against in D&D4 are gone in D&D5.
D&D4 really was a weird system that felt completely disjunct to anything before, added the strangest classes, and had the weirdest mechanisms. It didnt feel like D&D at all anymore.
D&D5 has some very strong changes, but it still is clearly D&D, and many things that I was frustrated about in AD&D and D&D3 have been fixed.
Yeah, it was for sure different, at that time I pretty much only played 3.5 with my group for a real long time. So it's probably just something personal, as in wanting something new. For 4e to 5e, I only know a few off the top of my head: rituals, nerfed restrictions on small characters and warlord class. Don't remember the warlord class in 3.5 but I could be wrong, was told multiple times from my co-worker about that class cause, I tend to mention my bard in 4e that could move allies like a chess game. Generally I think the whole slide and what not that supported figures was really interesting. Also fun fact bg3 using weapon abilities comes off as a adjust version of 4e powers (a lot of the classes had weapon abilities tied to them).
