I've played mostly Mono Berzerk. and Iv done quite well.....considering I have every character released thus far. yes they have their flaws, but if you know how to use a clan well enough that u can Mono deck that clan all you want. But even i say, until Berzerk gets a sound DR it would be best to use clans like Uppers or Montana. Clans that help you conserve pillz for you heavier hitters
That clans all about damage i doubt they will get a dr or a + damage healer very soon poor clan but mono would be strong with a leader like briget or mourphum but all clans can be mixed even rescues. they may be +6 but there is sentenials that can mix with them.
