these are so much different classes
the bishop job is mainly to heal nothing else
With OL you buff your clanmates and immobilize the enemy

they aren't so different .. Their primary objective is to protect your clan/ally mates ..

again ppl that never play this classes comment them........
Bish must heal/ress/clean debuffs from his pt members/ or debuff/mana burn enemy, bish is good in 3-9 ppl pvp or pvp with much more ppl.

Ol is hard to xp char, you need always pt, for low rate servers in low lvls your buffs arent good. In high lvl you can choose to:
1. run on kamikaze to debuff enemies and to die.
2. stay behind your clan and spam cp/heal and to be helper for bishops. [On 1 server that I play we was 6 OLs in clan with 90 active ppl and I can tell you in mass pvps we dont even have bishops in half of parties and almoust noone from us die. When 6 OLs spam CP your clan CANT die (it was epic days of lineage)]
3. 3rd option is to combine 1. and 2. and when you support, buff, heal your clan to go to make debuffs on enemy (thats what better OLs do)

OL is char that every clan need, its better for mass fights, its also good in Oly and its maybe only char that without top items can own better equiped champs

i will say few things about both
to low/high rate

bishop
there is no clan that wont take u in (unless stupid)
u can level with having fun same way on aoe parties
you will flame the whole world at pvps cause most likely u will be in a retarded cp where tanks singer/dancers think their role is to leave u behind to do damage and not to protect you
then you will have epic momments of 3 daggers backstab u and non of ur party cares
oly beast, if plsyer properly most rivals wont have mp at less tha 15 seconds vulnerable vs daggers, kamels and anything doin tons of damage in little time,but nothing u cant handle

domi
will curse ur life more than the enemmies
THIS THINK REFUSES TO SOLO
TOO HARD!!
seals in mass pvp useless
seals in oly useless (except the third class ones maybe)
propably only seal worth doing in mass pvp is suspense cause it affects all (mystic and fighters)
better buff and cp heal
rest are silly things heal ur clan and see then pwning rivals

as the tard said, healing whole clans with some domis ROCKS
about oly cant say many things to judge)
he is beaten by bishop but he is better than bishop (bishop kills him but thats a stupid way
to pretty much drain to death everything
only things can beat u are summoners and maybe tanks and kamaels
rest are most times easy wins
