I think it is almost unanimous that some things need buffs. Which things varies according to opinion. Especially right at the end, SinisteRing nerfed many things. It's time to set things right.
So, let's start to compile a list of what needs to be buffed, and/or suggestions of how to do that. For the moment we can ignore Water because it has it's own whole threads.
Earth:
Hurl Boulder: Very situational now, and much harder to use. I suggest that it's range be increased to 650. Also restore the stun duration.
Fissure: Restore the stun duration to 2 or 2.5 seconds. This ability deserves to be good considering how easy it is to avoid.
Erupt: Put it back up to full speed.
Armageddon: Reduce the self-damage to 100% and reduce the mana cost by ~50.
Earth Morph: Remove and replace with something good. Either that, or actually do something to scale it. In either case it needs drastic changes.
Interrupt: Still kind of weak, I think it should continue to do .5 second stuns every 2 seconds for 6 seconds. (So a total of 1.5 seconds more stun spread out over the next 6 seconds.)
I am stopping at the Earth element, but I will do more later. I would also like any suggestions from other people on the elements that I am not as familiar with. (Lightning and Fire.) Or really, any element you think needs buffs to something. (Besides Water.)
