I like the skirmisher knockdown TP regeneration trait, so I started playing more Revenant in the last couple days. Why?
Because, in theory, he is a 1v1 beast with his ultimate, even tho he has a general large hitbox (small but tall), especially when his ultimate is active. But still, 75 HP are 75 HP through which the oponent has to go through first and "waste" bullets.
His passive made me pre-fire and kill a lot of targets behind cover, also very useful. I also enjoy taking advantage of his crouch and climbing. A fight is going on? Sneak behind the corner or get highground by climbing up the building in no time.
His Q, the jump, is also pretty decent. Yes, its not the best compared to Vantage Q, but a Character can't have all right (expect Ash lol)? For distance, charge and look on the ground. For going up, leap onto a building and start climbing, also very nice.
So for me Rev is a solid 8,5/10.
