The sun breaker was op, but now it is a bit weak, blade dancers might be ok if used by the right person, but for me are also a bit weak. Warlocks are not necessarily op, but the burn effects for sun singer are crazy and the storm caller should not get a fist of havoc plus a roaming super, which is exactly what the landfall perk is. It will never be balanced, but I would never thought the warlocks would be do powerful.
