It really feels like you just personally hate bubble, but you’re fine with shaman’s utility. The “nerfs for thee, not for mee” mentality.
We can agree to disagree - but you’re agreeing to be fundamentally wrong. Classic era WoW doesn’t matter - this was discovered two decades ago. I didn’t make it so, the game did.
The “pvp changes” you’re discussing were actually PvE changes - with the exception being Scorpion Poison being bugged and having to be fixed.
Starsurge change was to give Druid a realistic mana cost and rotation. Kill Command was to force Hunter into an intelligent DPS usage instead of auto cast. SW:D was because Priests were using it per cooldown in raids and smashing DPS meters with it.
None of those changes were actually due to PvP… They just happened to effect PvP because those abilities were outliers in strength. They were all done with PvE focus.
