Before I give my personal opinion, can you tell me whats the thoughts of your own build that go to PvE with Wiz1>Cryo2>Linker1>Psychokino1>Runecaster>Featherfoot? I dont mean to be offensive but this build seems suxk to me.
My personal view:
Cyro does not combo well with Linker. As JP will link your own IceWall and waste the link target which is suxk. To be honest I very less see there is a Cyro+Linker build. If there is one, it must be cyro1 -> linker2 -> (other support).
Most people if they go cyro2, then they sure go for cyro3 for the ultimate CC skill (the frost tree something). I think you better dont miss out the skill as it is really really strong in dungeon run.
Cyro is more like a CC as support rather than damage class. Its known to be a pain to level it up as a support without friends leveling together (carry you). If you want solo while want some damage, I guess you have choose a wrong class.
