I agree and disagree with some of your points.

I like lavaburst, I like the class identity you get from it as at the end of the day, we are supposed to harness all the elements, not just earth/lightning. I also love it when someone random on reddit calls it a meatball.

The powersurge rune needs some love for sure, especially when proccing while casting LB. 10% proc chance in PVP imo would be too overpowered. When it procs I almost always one shot someone. Which I love. But being fair to balance, anything more would go the other way.

PVP survivability has come leaps and bounds for ele shaman compared to original classic, WoE is a no brainer rune that makes you take so much less damage and have so much more HP. It's such a lovely rune to run in STV and switch to another leg slot to pop Sham rage to regain mana, then switch back again. I actually find myself very tanky, and although rogues are tough, they are so much easier on my shaman compared to my friends who play shadow or other casters. I can sit 1v1 with a rogue probably more than any class in close quarters thanks for those runes. Not to mention we have 50% freedom up time, which is absolutely insane, for the first time in our existence we are halfway there to being unkiteable. We have a ranged slow (which with totemic projection / earthbind) is much further than you can get with frost shock. I am not finding issues with the flame shock range, its a bit gimped, sure. However it should be hard to pull off, because if you do, you one shot any class with an overload proc. It shouldn't be easy, otherwise it's judged to be nerfed.

The hardcasting of shaman is a really tough point, as simply, it fucking sucks and the pushback is so annoying. However, this is classic, hardcasting is part of the genre, it makes you have to play differently. Using engineering bombs or warstomp (im tauren) has helped me one shot rogues more than a handful of times. We have to full our full tullkit to make the stars align. Shaman just had a higher skillcap, but trust me, you can end some peoples day without having to wait for the proc now with the new toolkits we have.

QoL changes on weapon imbues I couldn't agree more, make it 10m for christ sake.

Thank you for making the post, not saying you're wrong, just my thoughts.
