I spent all my life on maxing a warriors def then got shotgunned by unicorn in clands lol

damn dude... the unicorn boss is a bitch....

How do you mean by this?

first off... that is terrible grammar... secondly leave current guild, find new guild. Really not that hard. If your guild is dead then clearly its not doing you any good to stick around

Neither have I :|

Grammar forum says otherwise

What do you mean? asks for a complete explanation. The speaker did not understand any of what was said, or understood very little of it.

How do you mean? asks in what way what was said is true. The speaker understood the main idea of what was said, but wants clarification of the sense in which it was intended or how it applies to specific situations.

Some people do occasionally use "How" instead of "What", or "What" instead of "How", but the usual word is "What" when you ask what someone means -- unless you are really asking for the sense in which what was said is true.

Warrior or Knight?

I'm looking for something to do Abysses with and other dungeons like oryx and wc.

Knight seems better to me but seems a lot more boring then the warrior.

I have literally never heard anyone say that in my life. Im going to agree to disagree. "What do you mean" = full explanation "What do you mean by that" = minor clarification. Of course you are more than welcome to find a grammar source corroborating your explanation.
