I do agree that raid content is too simple and must be buffed. I was a hardliner on No Changes, and honestly I have to say I regret wow classic gold. Now I'm only raid logging until TBC comes out. The matter isI had high hopes for WOW Classic and has been kind of let down, and I feel the same thing could occur with TBC unless they lighten up and manage WOW Classic. How should it be managed by them? That remains to be seen. As I didn't understand how bad WOW Classic was likely to be before, I don't have the foresight to understand how bad TBC is going to be. That's left to people that were smarter.
You listed five reasons why"spell batching is destroying PVP", however you reveal very little understanding of how it works. We can proceed through every one of your examples point. Though this is brought on by spell batching, you must see that retail WoW has spell batching. It is only that the spell batching window (i.e. the interval of how often spells are processed server-side) is reduced greatly. As long as any kind of spell batching exists (which it pretty much has to) moves like this are possible.
WoW has a spell queue window for your keypresses, which means that you can get your earth jolt to cast at the specific time as the lightning bolt throw finishes, so even if the spell batching window was 1 ms you'd have the ability to get lighting bolt and earth shock through at precisely the same batch, with both benefiting from Elemental Mastery. Just like above. Additionally this has been a core part of all mage gameplay for years of ancient WoW, it is odd that it's destroying pvp.
Nothing related to spell batching. Sap breaks based on harm, not debuffs. Shot doesn't break sap, and thus doesn't cause damage on its own. Same as possible blind, use, and fear polymorph a lot of other CCs on a sapped goal. The trick is to prevent auto attacking or via angling your cheap shot. Is not due to spell batching. It's due but the packet containing this information using not reach Blizzard's server however before the Counterspell was processed. This also happens in retail WoW by the way, even arguably to a larger extent because of Blizzard having implemented a"kicker's benefit", meaning that if the individual was still casting in your screen once you pressed an interrupt, cheap classic gold wow is going to be succesful.
