We are talking about a specific setup of class (ranged), "elites" (the hard but killable ones) and area (open space, where you can kite)... and Blizz increase repair costs by 4-6x for that?
About mortar... you want to increase its range? Ok, give it the same range as a DH, but please give us a zoom out option, so we can see what's happening.
It's silly that you can kill and get killed without seeing your enemy.
I'm not a melee expert, but I saw vids about monks killing Diablo and any other inferno encounter by just using Blade Storm and Fists of Thunder (+heals when needed) way faster than any ranged will ever be able (inferno Diablo in 4 minutes or so, counting cutscenes).
Are "non godly" geared melee so much worse?
