Answer:
Shamans can make criticals way more than evolved shamans, but when it comes to PvP, shamans are history.
Shamans can do one successful critical with dry lighting, but only once and a few more after that due to bad mana regeneration, the shaman has to rely on the first 2 attacks which do a critical.
Evolved shamans can use freezing flame to stun the shaman so who knows if that guy's lucky enough to use dry lightning. Once the evolved shaman stuns, he doesn't stop that easily. So ultimately the evolved shaman keeps stunning until the shaman loses.
So in this guy's opinion, evolved shamans are better. Here are some genreal tips:
Shaman: A high damage dealer. Cannot solo or heal. Bad mana regen. Needs team to help survive all the time. Can deal criticals overtime.
Evolved Shaman: Great team support. Can solo efficiently. Cannot deal high damage. Can heal pretty good for the team, can stun very nicely. Has a nice buff and debuff. Better mana regen than the shaman. Usually relies on freezing flame for damage.
In the end, it depends on how well you can play either class.
Note: Shaman is the best just get 3 wiz 1 luck or 3luck 1 wiz is good enough
Shaman may have a lack of mana but not that bad. so i suggest SHAMAN IS THE BEST
Another Note: It is been Discussed that Original class is the best.
