Regulus scales far too poorly, or just generally.
When I was level 1-10, I was the meanest bitch on the map. But when you get to level 18, that 900 damage just doesn't cut it, and it never goes up. Same for the mines.. if I laid those suckers straight on a Demigod, he would be half health. But obviously that damage never goes up. Now they are level 25 and buy +4000HP items or whatever, and these skills, they just don't cut it. This makes the endgame basically pure stats spam. The damage of abilities should scale per level once the fourth rank is reached, or per some other base stat to keep their relevance. I was sick of running around and sniping my opponents to find no significance.
