Next, everybody is thinking that everybody will be heavy and sit in one spot and maul everybody down
What next? Mediums will be overused because everybody like's assault rifle?
Chill out guys, the game is balanced perfectly. This isn't a rail way system game where it's impossible to flank, every size will have it's use and their will be no class or size better than another one. You may be good at something and think it's more powerful than the rest, but rest assured that somebody will come and proove you otherwise. From what I've seen in most gameplays their is usually at least 3 paths at one time to travel and reach objectives. This coupled with the new battlefield trailer that just came out today just prooves to me that gameflow will be seamless.
Relax guys, all will be fine. Get a breath of fresh air every once in a while, because the dust in your room is starting to make you all not be able to think strait. And that's a saying, not a flame.
