I just went back to BF1 last night and I don't imagine I'm coming back to BF5 at all.
There are no noticeable glitches - at all.
It's noticeably slower, soldiers do not run as fast as they do in BF5, this is a big deal for me, it's only slight but it makes a huge difference. BF5 is too much like COD in this regard imo.
The map design and modes feel very well planned out, I can strategically and carefully position myself facing an objective knowing no enemy will randomly pop up behind me. In BF5 with people rushing all over the map with no apparent strategy and just hoping to run into people by running everywhere, well it has a massively different feel to the game.
The graphics are not a step down, they are equally as good.
All the game modes are there, I played rush for hours. I can be certain that when I play later today, no modes will be removed without any given reason like constantly happens on BF5. This here really finished me for BF5.
The lobbies are well populated, like extremely well populated - the same as if not more than what we see on BF5.
No disappointments or endless delays, the game is solid and there's no constant nerfing and boosting, just a great game without any of the nonsense that goes on around BF5, none of it.
Now I can take BF seriously again, I can't recommend enough to others that they give it a try as well.
