There is something you are overlooking about Aragorn drhouse, he can use Blademaster WHILE mounted on Brego. No other hero in the game has both a mount and blademaster, except Eowyn, but hers only gives armor, and only small armor against non hero damage. Aragorns Blademaster remains one of the best slayer type powers in the game, giving a great armor and damage boost against everything, combined with a mount, makes him one of the most formidable hero killers in the game, who can also do great damage against units. Don't forget about Elendil either, scattering armies to escape or allow your armies to pick them off while they flee can be devastatingly effective, and I have used it to decide battles. Like I said before, you are asking for too much, and if you ask for a complete overhaul its not likely to happen, and frankly, it doesn't need to. He just needs a bit of a tweak for his final 2 abilities at level 10, he doesn't need a complete overhaul.
