You can definitely tell some of the UI and spawn/weapon/etc ideas were taken from Battlefront, although thankfully they didn't dummy down the weapon choices and customization as much as BF did. So yeah, I could see why some people are gonna hate it since it feels easier/dumber than BF3 and BF4, but I dunno I haven't had any real problems and I like some of the stylistic stuff like the swoop in when you pick a spawn point or the sandstorm effects, which seem better than BF4.
Sniper is definitely a problem though, it sucks when you get a team full of sniper camping fags on either side. When you get a team that gives a shit about the objectives its fun as hell though, especially with a squad leader who is smart about orders you can rack up MASSIVE points just by capture/defending - I had like 11k in one game with 3-4 kills, just a ton of captures and recaptures. I find it best just to spawn a new squad and be its leader if you join one that has a shitty leader, you can rack up way more points.
I don't mind the map at all, while the wide open spaces make sniper bitches a pain in the ass it also makes it fun to ride around on horseback or practice low flying. Definitely has a Lawrence of Arabia and Tatooine vibe going on. Not really sure of the WW1 vibe, I don't really "feel" like its WW1, as people have said it feels more like WW2 with the vehicles and insane range sniper guns and huge mag assault rifles. People will disagree but I wish they had gone all out on alternative-history timeline, with tesla weapons and shit like that but all close quarter combat and trenches and glass cannon vehicles/siege weapons but maybe that belongs more in a WW2 game.
