I still prefer vanilla over Bfa for sure. Bfa gameplay right now is terrible and vanilla would be an upgrade. But there will be things that might ultimately make me quit classic servers :
1- No aoe loot : simple but important. So much time will be wasted while you aoe grinding and you have to click on everysingle creature you killed (shift click btw) and loot them. In long run it might waste a day of game time because of this. Smh.
2- So many simple addons : i know there is a big crowd about #Nochange but most of those people if not all will have the addons for quest tracker , hp tracker , gear compare , even simple mailing and etc addons to add functions that are in retail to classic. Lets make these stuff a toggle instead of outside source addon.
3- many specs are jokes : if blizzard doesn’t balance weak specs in vanilla most classes would have 1 playable spec which results in lack of variety in playstyle in the long run. Only warrior would have 3 playable specs good for them i guess.
4- models : it would be fun to play with old models for couple of weeks but after that it will start to hurt the eye. While we adding new graphics models should follow suit.
These stuff in the long run might or might not make alot of players burnt out. At least we gonna have alot of players in the first or two months.
But it will feel good to have a wow without blood elfs yay.
