maximum of 8% health every .5 seconds, wow so strong.
its basically just a larger tibbers without the burn effect, its just an eye sore to people. it will most likely be used for just taking towers, dragon will tank the turret.
dont get me wrong, it can impact in the team setting for sure, if it gets even just 5 AoE attacks off on a few people, big difference, but the enemy team is much more likely to either blow morde up "as hes an immobile carry, not a tank", or they just ignore him for 45seconds, and they'll come back a little bit later when you dont have your ultimate still (120 ~ 90sec cd)
and what if the enemy team is doing dragon at the moment? is morde going to go over into their group and take it? it basically forces a team contest or he will die trying.
