I used to use the right side shaman because I was lazy and just liked the increased mobility etc. It was a pretty big DPS loss not having the ability to crit on dropping a totem & fire orb dot dmg but whatever. NOW, that you can literally shoot 4(+?) orbs out of the lightning totem using the left hand side, there is basically no excuse for going on the right side of the tree. Unless you purely use it for running around the map and climbing to heaven. So yea, right side shaman was already trash and now its even worse than trash comparatively lol. Similarly they wasted time making interesting things like hex totems that can never be used due to how class abilities are currently setup. Nobody is going to drop DPS for a hex totem. Why is there not a realistic way to use a support totem like hex or the defense totem without sacrificing obvious better choices?
semi related to trash talents I still argue this:
Orbus almost made a cool class 
If they are not going to remove or heavily alter classes at this point, I’m in strong favor of having prestige classes that require for example a level 20 or 30 shaman & pally to be able to start leveling some not poop class. Shamadins baby.
