I think some of the skills are a bit underpowered compared to the other classes. They may have great effects, but there are things hindering them.
Mana usage is major to this class and the main regeneration skill is only active for 3 seconds while the cooldown is almost a minute. Some of the skills should get more range and AoE like the stomp skill with stun and debuff. 3 meters is very small for something like this. The healing is working great. It may not be a super big heal like the mages but it keeps others alive. The birds could stick around a bit longer. 6 seconds seems a bit small.
Palidans are still fun to play though through all of this.
