You were talking about tanks. You compare them to tanks, thinking tanks are highly indestructible. Regardless if a "tank" class from an MMO is your idea, they got the idea to name it and base it off a tank. Either way, what I stated is highly relevant. There are many ways to kill a tank, all relatively easily. There have been Men on many sides during ww2 that have destroyed multiple tanks on their own in a night. Translating to: it should be easier than nigh impossible to kill a sunbreaker during their super use.
