I'm also a fan of Aion 4.0 and below, however I don't know how dumb you have to be not to find the flaws in aions battle system and netcode and aion classic kinah call pretty much high 3 pvp mmorpg. Everything you listed under"ability" is a part of majority of PvP in mmorpg, it particularly looks very like wow...

The only thing it has going for it is that becoming to maximum level is a travel, everything is quite difficult, in classic particularly it will be quite slow and nearly impossible at times to progress at an suitable time with no party especially during 16-18 because kralls hit such as trucks. PvP feels special because that's pretty much all there's to it at the end game witht the exception of running a few sponge dungeons and raids largely for the enhancement products, or gear that you would sell to buy enhancement products, the caliber of PvP is not the best, it reminds me a lot of GunZ playerbase where they think it is the best Third Person Shooter but in fact that match has such massive issues with the quality of the gameplay you just wonder how can anybody thing which, same thing happens with PvP in Aion.

The most important selling point of this game is not even that much of a high quality, sadly. If developers put time to the releases of their classic variations and actually had love for the game not a pure fiscal motivation, possibly we would see these obvious issues fixed, and in the event the clunkyness could be fixed, it would really be among the best PvP games on the market.

Far from Precisely the Same thing for a GCD. Animation duration differs from skill to skill which is the opposite of"global". Also as mentioned in the top comment, there are tons of technical hints revolving about animation that when mastered, puts you in a huge advantage depending on the class you are playing. For example a ranger who doesn't understand how to slideshot or jumpshot will not be able to kite nearly and a person who does. A sin who does not AAC (automobile attack cancel) will be pumping less out dps and decreasing their opportunities at a godstone proc. Other courses AAC also but because of the difference in animation duration, the timing is totally different. Thus again, not even close to be the buy aion classic kinah eu exact same thing for a GCD which forces you to wait for a fixed amount of time between each skill if you don't have haste.
