Just a few ideas.

I noticed there is a dotted yellow line when you select a target, maybe have a range finder with it or just have it next to the name of target? The skills have a range but it is hard to judge in game, having 6 bad guys charging you and hitting stomp to soon and wasting it just breaks my heart lol.

So sort of crafting of course I'm sure there is a thread somewhere on that.

A dps meter would rock!

There was another thing that eludes me as of now, bah!

the range of abilities you just get better at judging, there is no real ruler idea floating around... use a few more stomps and you will get a feel for the distance lol

Well with the stomp let's say, I think the power throws me off like the range is x but depending on rank they go y away from you
