This post made me think about a tank hero that does more than just standing around, hoping to draw damage from the AI controlled heroes.
The idea would be a late threat like Cinder. His weapon would deal low damge to opponents, but good against cover. He has , as you would expect from a tank high HP and high deff.
Bronze Skill: A slow charging, but hard hitting skill. It takes about 45 seconds to charge, but deals ~300k neutral damage and is unavoidabel, but has some cast time, so you can block it.
Silver Skill: I would like to see Yanlongs skill or similar here. He slowly builds up his defense to the point he can even tank two damage dealers if he survives the first Minute.
Maybe instead of the armour he would gain a damage reduction and extra HP.
Gold Skill: Each time he hits his Bronze the cooldown gets reduced by 20% and he provides XX armour to his team.
This should make him really dangerous towards the end of the match.
Platinum Skill: Something similar to Ronins Gold. Each time the team breaks a cover he gets some extra damage to his Bronze. If he hits it, the extra damage is lost. The next broken cover adds damage to the next strike of his Bronze.
The high charge time may seem to make him useless, but remind that he adds extra damage with his Plat. So he can one hit squishy opponents.
Numbers are open for discusion, but I think a tank like this would do a lot better than the tanks we have now.
