I feel like melee in general is a lot of running from guy to guy, killing them off one by one in about three hits while being bombarded with a hail of bullets from every angle. It's slow and gets tedious. Especially as your suppression goes down. Perhaps I'm hoping for a faster pace to the game than is intended. Though the ranged pacing seems quicker.
I feel like in a big mob of guys melee should feel like you're chainsawing/hacking/sledging through a grouped up bunch of meat watermelons. But the cleave abilities do not do that. You're lucky to hit two guys at a time, luckier still, you might hit three. I feel like the arc and the range needs to be bigger.
Another problem is knockback. I had a situation where I was able to hit two guys at once with my cleave. Which is about the best I can hope for at the moment. The cleave hit them both, and knocked back one. I got 4 swings in before the knocked back guy was back in range to be hit. And he didn't really get knocked back very far at all. It would have been just as quick or quicker to kill them individually.
In my mind if you're slow and under constant fire, jogging from guy to guy and maybe getting a few clumped up packs, you should be a wrecking ball of destruction once you get to them.
If rocket jump is supposed to help with that mobility it needs some attention. You can't go very far, there are pathing issues, and the animation time and speed of the jump means you're really not getting anywhere much faster than if you just ran over there. It would be cool rocket jumping or rocket charging from guy to guy or group to group and getting that real sense of satisfaction with sound, visuals, and damage when half a ton of heavy armour and a humongous shield smashes into them.
