@speedwagon: im going for a priest, its interesting cause the 15%seal resist priest gets makes it a total of 20% since it is water(5%resist). i cant realy give you tips on builds though.. im trying my own thing and since im only lvl103 i dont know if its a good thing :D

Im stil kinda new to this game so the more experience players can give you better advise, but here is how i see the builds:

it just depends wat you wanne do with it. sealers work best if they are faster then mobs. so if you want a pure sealer, id go for a seer or wit. wit cause it makes your seal more effective(more int), and you get a good js. seer, cause it wil make you faster so you can seal at begin of each round(i dont know if its also required for quests. Might be more a pk sealer).

for water the seals freeze and sleep only last 2rounds. So if you seal after the mob moves, you only sealed them for one round, and it is kinda useles. since you sacrifice one round to seal for only one round. Therefore agility is important and id advise a seer.

IF you wanne make a tanking water id go for priest. with lots of con and wis he will be the last person in team to die, and able to ressurect everyone wen needed. i pk'd one today to see how it is, and we had same MatK. i dealt him 300dmg while he dealt me 800... lol. he could easely overheal me. He might seem less good couse his seals miss more and his dmg is wel.. bad. i stil can see the importance of it. As a water, being the only character with ressurection... your not supposed to die before the rest.

anyways. just how i see it. pick what you want. play how you like. And if the build sucks... just make it a farm and restart on a new character:P
