Yea if you go rogue what you want to do is get these skills:
Res = Resing other people in party when dead or when full support died.
Bless spell = Very helpful when about to die and in pvp big extra boost in def.
Healing cycle = To help you get to level 40 for Recovery division its a 16 second heal very helpful to.
Recovery division = Is a 300 second now and then heal its like your alway sitting down getting your life back best skill for a rogue/cleric .
Other skills that are optional :
Heavens flash = For people that are trying to run in pvp or thieving, hunter etc...
Holy word = Reduce's damage off things like fire, lighting, statues effects
very good in pvp . ( And alot of mobs that do them like crazy )
and thats all for the rogue / cleric build and if you like max out all rogue or just one like crossbow hope i helped
