You didn't give us any information, such as current progression, what content you need to do, etc.

With zero other information provided, I would recommend quake. Though you have quite a few solid options to pick from.

You literally cannot go wrong with guardian or warlock.
If you want insane damage and moderate utility, guardian.
If you want insane utility and moderate damage, Warlock.

You don't have a Super High non-bleed burst champ at rank 5, so I would invest in either Guardian or Professor X.
If you want a simpler gameplay loop, then guardian for sure.
