Absolutely.
There are also plentiful choices in regards to enchancing melee capability, caster capability, and tank capability.
It’s not the difficulty, its the return on investment.
You specifically mentioned Resto, which is what I was addressing.
During Classic having an Enhance use SS and then just twist makes sense, with current scaling for melee, and the lack of scaling for enhance with shocks.
However in TBC group composition is different. If you have a Hunters group of: BM, BM, Feral, Resto/Enh, and then say a Ret. It means your only twisting for 1 player.
Thats 2100 mana per minute to gain ~160 DPS in Tier 5 on a Ret. You are limiting available cast time AND you have to twist at certain intervals.
Or you can just have that Shaman cast Lightning Bolts. That’s 7 bolts, cast in less time, cast for the same mana, cast when you want, for 120 DPS.
With Natures Blessing, ie INT > SP conversion, plus 1/3 of your healing also delivering +damage…a Shaman even in Tier 4 will have +500 spell damage at least, and increase crit to lightning spells to counter spell miss.
Conversely twisting in a tank group of RSham, RDruid, Prot War, Prot Paladin + Lock + Imp / or extra DPS also isn’t worth it.
There is no new Rank of Grace of Air. And thanks to new Agi scaling in regards to Dodge and Crit the gains towards DPS aren’t that appreciable.
Warriors, Shaman, and Paladins now need 40 Agi per Crit percentage…in Classic that’s 4.45% crit…in TBC that’s 2.23% crit…for at best 4 players and frequently less.
At least casting LB can be done when you want, it can be ducked if someone needs your attention, and it’s more fun than watching an Aura Mod timer for WF.
The gains aren’t there in any appreciable degree for Resto. And in Tier 6 it’s not really going to happen anyways.
This analogy is horrible.
Winning is Raid vs. Mob.
Killing a boss 10s faster is internet ego run wild, on a 15 year old game.
Which you accomplish by telling people the class they love to play sucks, or they have to endure doing something they detest or resent in terms of play style, to kill those few precious seconds faster.
