extra creep spawn makes the game 3 times easier. It becomes uninteresting to play due to the fact that the level grows faster and the abilities deal 2 times more damage due to the difference even at +1 level.
You can also climb to the top where the bosses won't touch you.

Tiny became very strong at the last ult level. (bug with attack speed)
Trent is not changed at all there is no damage at all and no healing either
