You recorded five reasons why"spell batching is ruining PVP", yet you show very little comprehension of how wow gold works. We can go through each of your illustrations point by point. While this is brought on by spell batching, you must understand that even modern retail WoW has charm batching. It is only that the spell batching window (i.e. the period of how frequently spells are processed server-side) is reduced greatly. As long as any kind of spell batching exists (which it pretty much needs to) moves such as this are possible.
WoW has a charm queue window to your keypresses, meaning you could get your earth shock to cast at the specific time as the lightning bolt throw finishes, so even if the spell batching window was 1 ms you would be able to acquire lighting bolt and earth shock through in precisely the same batch, with both benefiting from Elemental Mastery. Same as above. This has been a core part of gameplay that is mage for many years of early WoW, it is strange that suddenly pvp's being ruined by it.
Nothing to do with spell batching. Sap breaks based on damage, not debuffs. Shot doesn't cause harm by itself, and thus does not break sap. Same as you can blind, utilize, and fear polymorph other CCs on a sapped goal without breaking. They key is to prevent auto attacking at precisely the exact same time as you cheap shot, which can be accomplished through macros, or through angling your shot. Isn't because of spell batching. It is due to the particular person who had been casting a spell stopping their throw, but the packet containing this information having not reach Blizzard's server prior to the Counterspell was processed. This also occurs in retail WoW by the way, even arguably to a greater extent because of Blizzard using executed a"kicker's advantage", meaning that if the person was casting in your screen when you pressed an interrupt, it will be succesful.

So along with the package comprising the spellcasting being stopped needing to reach Blizzard's servers it would also have to accomplish your computer. A hard limit is to this, so after casting ceased someone playing with 1000 ms can not interrupt you a second. So you will have a problem with this due to latencies between the WOW players and Blizzard's servers. The question is simply which direction it triggers difficulties in, i.e. are you getting upset after you already stopped casting, or are you using an interrupt while your enemy is projecting but them not becoming interrupted owing to your enemy stopped casting on their screen.What differences do these offer both? Are beginner friendly? Are the communities? Retail WoW is not really an MMORPG anymore. It is queue-up for articles game with no social interaction what so ever, just a hub based. You are insignificant and have no effect or influence on other WOW players. Folks basically just phase out and in to give the illusion that you share a world when in fact you don't to you. WOW Classic is an MMORPG. So if you're searching for an mmorpg, I'd pick at WOW Classic. That said, Albion Online is an even better mmorpg.
