Inferno should be relabled gear check mode. It's a bit annoying because to do well in inferno you need the gear that drops from inferno above any other factor (including player ability).
What do you do when you fight elite packs with any of the following abilities - waller, arcane, teleport, molten, mortar, shielding, freezing, etc? I'm going to kite them all the same. I cannot survive the hits even with most defensive abilities. The additional abilities added to the mobs do not really change the way I fight them in a real substantial way. Teleport out of danger and shoot at them. I feel that the original intent for abilities on these mobs was to change the kind of threat they possessed and thus change your play style versus a given threat. At this point it only seems to be a matter of choice between "kite it" or "avoid it." I would say "fight or flight," but it's more of a "flight or flight" imo.
More about the gear - I can do runs through Hell Act 4 and only find 1-2 level 60 blue items (I don't think I found a rare 60 in hell yet) throwing on the MF gear when I can as well. So to progress into inferno you sort-of need those huge DPS weapons we see on the AH for a pile of gold that only drop in inferno (or crafted from level 60 items which drop in inferno). One of the cases were you get what you need after you get there? This makes "progression" seem a bit backwards.
How did the first players get that gear? Perhaps some of them were dedicated good players, but how many of them took advantage of now broken play styles to get high end rewards even if they die a bunch to get it. I wouldn't mind dying 20 times in a row if the items that dropped were able to tip the scales in my favor for a while.
