I've heard alot of QQ about elemental scaling in 25man raids and have just noticed it myself when my ulduar geared DK (that i recently brushed off and starting goofing around on) was almost on par DPS-wise with my 2pc t10 somewhat-icc geared shaman. This started me thinking about how I personally would help Elemental shamans with scaling...
-note- I'm not really comparing talent trees at all, I don't have the time or brainpower to think through all of that
All other caster dps (Shadow Priests, Warlocks, Mages, and Boomkins) have a talent or ability that allows their spell power to scale with some sort of other stat:
Warlocks have http://www.wowhead.com/?spell=47893
Mages have http://www.wowhead.com/?spell=43046 for all specs and http://www.wowhead.com/?spell=31588 for arcane
Shadow Priests have http://www.wowhead.com/?spell=51167
Even Boomkins have http://www.wowhead.com/?spell=33591
So even at similar gear levels, we gain only from SP while all other casters benefit from SP and other sources.
Would it be so hard to implement a similar ability for Elemental Shamans since we are the only caster without this type of scaling factor?
That's where my idea to fix scaling originates from: just like Arcane mages and Boomkins I'd have a scale factor based on Intellect (this would somewhat discourage shamans from taking cloth gear because "elemental shamans don't need cloth you wear mail" right? :). I would either have a talent similar to our resto tree's http://www.wowhead.com/?spell=30869, or simply add an int->SP factor to ToW that only affects the Shaman dropping it (if it was raid-wide it would probably be too OP and kill the idea of raiding with a Demo lock).
This is just the ideas rolling around in my head this afternoon, but I'd love to hear how mmo-champ shamans think they would help ele shamans scale maybe a little better
