1) Carry weight - isnt rly matter, couse you can send all unnecessary things to camp with 1 bottom.
2 and 3 - yea it give a bit of thigs but not rly necessary
4 Cleave? what this one does?)
5 - jump dats good, but i use it mostly to go out of combat or change position when near more then 1 enemies. I dont feel dat jump distance rly matter in battle, and out of combat we have spell dat x3 distance.
