The gearcheck isn't likely to change, it's how diablo is..you're supposed to mindlessly grind for gear / upgrades so you can kill the next boss. It's not even cleverly disguised in WoW, you farm what you can till you get gear to move up to the next farming point.
WoW had a more lenient curve regarding difficulty/gear, standing in the fire wouldn't instakill you, and you could avoid the fire; in diablo the fire instakills you regardless of how good your gear is, and you can't even escape it; especially with all those CC affix rares and elites.
bosses were laughably easy, especially diablo is just sort of sad; the entire build up of him portrays him as a scooby doo-esque villain (as well as Azmodan and his stupid smug head appearing all over the fucking world), and when you finally encounter him after spending like a thousand hours kiting shitty mobs (which you all have to clear, i remember i encountered my first elite on act II inferno and decided to kite it into the fog of war, which ended up being filled with those annoying wasps that turn the game into fucking
Ikaruga, i only made that mistake once), and then you finally fight diablo and he dies within like 2 minutes after kiting him around from a distance, then he drops some shit loot which you can't use and sell and it's supposedly the idea to play inferno all over again. no thanks blizzard, i would rather wait for the shitty unbalanced PvP to come out.
