The damage is VERY healthy for PVP. The environment is far better when people actually die.
The thing about these combos is that they're all blockable and dodgeable. Outside of being ganked from stealth, you always have ample opportunity for counterplay to them. That is the exact kind of high damage we want to see - direct damage with good counterplay as opposed to dot/proc damage with no counterplay.
This game was at it's peak when anyone could one shot eachother with a dswing -> leap or incap -> bow style combo. It's nice to see we've made some progress back towards that meta.
