I like the high TTK from a pilot-vs-pilot standpoint (not the mode, just the engagements).
However, it only makes it clearer that the melee needs a massive fix. Nothing ruins the fun for the 'dance' - where players are bouncing back and forth, evading each others shots while trying to land their own - worse than a homing melee lunge from 10 feet away.
I'd also add a shield to every newly spawned Titan. Even if they're not the recharging variety.
Boosts are neither here nor there for me. If they're gone, fine, if they're brought back, fine.
