what is the best class i can buy with 2000ac? the strongest in terms of how much damage it can do in one hit
You should get classes that are limited time only (like Ultra Omniknight or Abyssal) since pretty much any other 2000 AC class is obtained by farming something (like rep or miscs). Omniknight does insane damage with insane sustain so I would recommend it.
Abyssal Angel is decently strong, has AoE, and is going rare. Almost every other class in the game right now you can farm for, so I suggest getting Abyssal Angel.Like Megenhos said, Omniknight is really powerful too, but I'm pretty sure you can still obtain it by farming.
Better keep the 2k ACs for some rares from Dage. I recommend only bot for stuff, not worth paying for a class, which you can get for free, just by leaving your computer on over night.
I agree with Hanh, It's not worth spending 2k rc for a class. It's worth by botting for it. The only class I know is worth buying with 2k rc is Blaze binder.
The only class that you should buy other than ones going rare is Blaze Binder. The only reason for it is it takes absolutely forever because you need to do a daily quest.
