After leveling shaman to 65 and testing out the PvP capability for the class, I noticed two major flaws. The slow has ZERO effect if the target is jumping aka 99% of everyone 99% of the time and this is considered our biggest ability in PvP. All that would need added is negative jump boost. This makes the slow actually affect those hit by it instead of them just keeping full momentum while jumping in a slowness 4 ability. The second biggest problem with shaman currently is the knock-up totem does not disorient as described in the ability. It simply throws the target up a few blocks every few seconds and does 0 damage or other effect. Adding nausea to the knock-up would give the ability the correct description. Cheers!
