I think it's no secret, and i think it's rather unanimous that Earthquake isn't well liked as our 31st Talent point in Elemental;
I for one; if given the choice would only go 30 points into Elemental, And I believe this is something that most people would agree with atm.
I for one find that giving us what is basically the mage spell Blizzard; with a smaller radius and a 'Knockdown' is quite a slap in the face as a 31st talent point; (don't get me wrong the ablity is 'neat' but it's not 31st talent point material).
So I really think it should be a trainable ability (if Blizzard really thinks we need an AoE spell that can be used in raids) And it should be replaced with something;
My idea for a NEW 31st talent point goes something like this;
Crashing Waves; (i was inspired to this idea by the Svaldir mobs in BT)
Make it something like a 1.5second cast; with the typhoon type graphic and typhoon-like feel, except that it must target an enemy and travels to them. It should have a knockdown to anything in it's path, and give allies a 30% speed boost for 4 to 5 seconds.
It would have a cooldown of course (something similar to thunderstorms); and given ele's mana issues on beta, it'd be cool to make it consume all your watershield orbs, or something like that. It could be glyphed to no longer knockdown/give allies a speed boost; very similar to how Thunderstorm works, for a damage increase or cooldown decrease.
This ability would provide a really unique Peel for shaman in PvP, It would give us a really cool and unique cleave-type Spell in PvE, and Lorewise it would bring Water to the table. Also, we could make cool Pokemon puns. BLASTOISE USED SURF, etc.
So as it stands something like;
1.5sec Cast-time 30sec CD,
Does X amount of damage to the target and to all targets it hits on the way to the target; Damage is reduced by X% for each target it hits. Knocksdown all targets for Xseconds and gives allies in the affected area a 30% speed boost for 4seconds. Consumes all watershield charges.
Proposed Glyphs affecting Crashing Waves;
-Glyph of Crashing Wave; Prime; Allies affected by the speed boost are also cleansed of all moving impairing buffs; The knockdown now lasts for X less seconds.
-Glyph of Currents; Minor; Crashing Wave no longer knocksdown enemy targets and no longer gives allies a speed boost, but no longer consumes your water shield (you still generate as much mana as you would otherwise.).
