does the priest buff and stuff like that?

None except one self buff that converts damage taken to MP.
(You lose MP instead when you get hit.)
They only get two HP recovering skills and to two MP transferring skills while the rest are offensive type skills.

Bishops are the only ones who can buff the team(and himself) by increasing their maximum HP and defense.

Buffs aren't so important in Wind Slayer because partying is very uncommon in this game anyways. Only in PVP and later GVG buffs have some real use.

no you get more buffs later on depending what class your moving to Increased Defense/HP Buff etc o.o
