One of the more controversial changes in 1.0.3 is the increased repair costs. The design intent of these increased repair costs is to make death more meaningful. One of the top arguments we see against the increased repair costs is "I'm already dying dozens of times to make any progress in Inferno. Don't you see this is going to make this impossible?" This concern is most often brought up by ranged glass cannons. Many melee players respond "increased repair costs seem fine" because they haven't been using death-zerging as a tactic. Melee can't easily death-zerg an enemy down, but ranged can. I don't think the answer is to make death-zerging more attractive for melee; I'd rather make death-zerging a less profitable strategy for ranged.
I'm having a little problem with this as it stands. I consider myself a relatively skilled player, and I avoid zerg-rushing / face-smashing my enemies as often as possible. It's not enjoyable to have to continually run back / kite a mob to my spawn point so I can keep smashing my face against them.
But as a Witch Doctor, there are just some things that I CANNOT avoid. Such as being walled off by an elite pack, then mortar-bombed or frozen forever. Other things such as Illusion + Reflect Damage kick my !@# too, and no matter what I do, I will die several times to a mob before I either decide to skip it or restart because it's just too frustrating.
Another problem is that I'm not pulling off the easy 100k damage (I know this is over exaggerating) that a DH or a Wiz can, nor do I have the amazingly tanky stats of a Barb or Monk. With complete buffs on (Pierce the Veil, maxed Soul Harvest stacks, AND Big Bad Voodoo, Slam Dance) I can only top off at about 44k DPS. Inferno is kicking my $%^ here and there, and the fact that I'm going to have to farm to repair my gear in order to farm again seems a bit outrageous. I don't see how this is going to bring balance to the classes, as deaths resulting in unavoidable deaths or impossible mobs are going to happen to everyone anyway. The only difference will be that we're going to be spending more money repairing.
But that's just my two-cents.
