Rhino can be beat really easily in pvp.
The reason for this is: No 12m skills (besides taunt which doesn't even work properly atm)
I noticed that the charge skill will not work if you are within about 15m of a enemy. It will just cast GCD and then ruin your combo. A suggestion is to make the Charge either 12m, or make it so you can charge at any meter but will only hit if it's 8m.
