@Lord_Scorpion34 Yeah there was a discussion about this on Twitter yesterday. Fuse is king early game when everyone has low shields, but once people move beyond blue his abilities (aside from the nade launcher) are worthless. Several times I've had 3-4 kills early game and then have not added to them even if I play for another 10-15 minutes. When I was maining Rev my kills were much more consistent.
He comes good again when it gets down to the final 2/3 squads and everyone starts taking cover. A double KC and a nade will send most enemies out from where they are hiding.
I had a game on Olympus yday where my squad got stuck high close to a respawn point as multiple battles waged on around us. I did 1,100 damage without firing a single shot including - a real rarity - a motherload elimination (the enemy had a choice of staying where they were and dying or risk running through it, which they did ... and died).
I'd still like his Ult to be less pants, but I think he's in a decent place.
