[...]I am powerbuilder by nature and always enjoy playing strongest, most broken builds in RPGs.[...]
I am surprised you consider yourself a powerbuilder but don't take the time to build it yourself. Sounds more like a power user since you seem to build off of other player's builds.
As other said, too many changes to give reliable advice however your character will probably need some Polymorth skills (skin graft), maybe you want Fane as starting origin to have the Time warp. Probably want high damage. Some player were able to solo with Warfare, Enchanter or rogue focus. I think you can have any flavor you want you just need a specific set of skills that are required for all.
