1. You have absolutely no clue how raids will work in D2 since you don't know the first thing about them, their difficulty, and what loadouts will be best to use in them. Stop. 2. Machine guns were *likely* removed because they offer the ability to get a LOT more kills than the other guns do given the ammo of all of them. Just a guess, but this is where I'd put my money if I were betting, and please don't act like it requires skill to get LMG kills. 3. I highly doubt everyone goes for rockets since shotguns and snipers being in that slot with presumably more ammo would offer an enticing option to people like me who don't really like RL's. 4. Trials is going to be 4's since Trials falls under the category of "All Crucible" and doubles will not exist at launch, because again...."All Crucible." Hope this helps.
