Hm. That ultimate is a bit confusing for a number of reasons.

First, the mana cost. For a strength hero, that's literally all his mana. Gone. Unless you invested in mana items.

Second, think of your teammates! If you have a really good push going on, this ulti will ruin it all. I can imagine a lot of trolls playing this hero and just screwing his team over with it.

Third, if the enemy isn't near creeps, it's...Underwhelming, especially if you used that amount of mana to do it. Hell, at level 6 you probably won't have enough mana to use the ulti

Other than that, I love the hero concept. A good job, as always.

Hm, yeah. I didn't really think that through. I'll make some changes! Thanks!

Much better :D
