I agree with you, they should have accounted for this when they decided to speed up the game. Or maybe they did and it was intentional. Either way, there is really nothing we can do but resort to cowardly hit-and-run tactics to keep our streaks going. It is sad to say, but as Bloody has mentioned 100 times, the game wants you to get a kill and then die.
And what is worse is when you die and you respawn and your allies are clear across the map and you see 3 red dots converging on
you. Being in that situation BITES. Between the spawning, the mobility, and the shield delay, this game moves almost (I said almost) as fast as CoD. The only buffer we really have are the shields in the first place. That isn't the way I like to play but I guess you have to if you want to like, play Halo with everyone else.
