My opinion so this may differ to others.
1)When I was in a game players were doing nothing so as I tried in chat to get ppl to do this there answer was this is BF and how it is, I then asked what was your 1st BF game, to witch he replied BF1. it started over ppl not doing there jobs or doin nothing at all, they should be doing there best to help the team and when I told them that this is why we play BF. I was told well not on this 1. I play BF for the team work and to at least try and win but that isn't the case no more. Thanx to dicer wanting to get the COD players into dice (which is a good thing) but most don't change to how BF should be played.
2)Grenade spam still is a huge issue and ruins the flow and feel of the games.
3)AA's still way to good, I love flying and fly as much as poss. but the AA's still make flying no fun
4)The game feels more like a COD game than a Battlefield game, just on larger maps. :-(
5)there isn't enough progress system that would help towards encouraging me to play more.
These are my opinions as a BF vet, I miss how battlefield game use to be. I'm nearly 30 and don't want a loved franchise to turn into COD. I play BF for the slower play, teamwork and the awesome vehicles. Dice keep up the good work but please DONT get greedy and try to satisfy mindless COD style of a games, Do your BF the way it should be done.
