Not posting champ builds means I cannot give you any advice on what to use. I don't know who would perform well, cause I do not know who is built well.

If you haven't left the forums as you claim, post pictures of the champs and their gear and stats, and I will try and make good suggestions for you.

Agree with Quinn that we need more information around champions and gear stats.  At a high level, I'd say that Kael (with lifesteal gear) and Scyl (healing, stun and resurrection) should be able to do the job if they are built right.
