As elemental with resto offspec i am SUPER STOKED for these proposed changed.
Spirit link, spirit walk, unleash flametongue, improved lightning overload. (mastery + changed overload talent for maximum pew) and earthquake.
Im reserving judgment on earthquake. It may yet prove to be copy of rain of fire or something, only with nature damage and different animation. That would be a disaster. Sure, ROF is a good aoe spell but it would be TERRIBLY boring if we just got a mirror of that spell.
Earthquake needs to be spectacular. Maybe do a slow, knockdown or siege damage as a cool secondary effect. Can you imagine the borefest if it was just a targeted chanelled aoe?
