Quite surprised to be honest, it looks actually really good. Love the change 4v4 brings to PvP, it looks way less chaotic and improve team work thanks to subclass abilities like the regen for the Warlock of the barrier for the Titan (but the Hunter looks like a solo player class).
Plus they simplified the way points are handled in Control, couldn't figure how it worked on D1 apart from the multiplier.
The level design looks garbage, hope there will be better maps in the final game.
The HUD looks so busy right now, don't like it...
EDIT: There is something I never understood which already was in Destiny 1:
Is this just a visual artifact/bug or do players have like a second small shield when they use their super?
