Do some regulars
Do some heroics
Max out with heroic Halls of Reflection.
Then do randoms endlessly for gear.
Is this 'alternative' progression? I see very little progression. I see loot. There's certainly loot. But that's not progression, or at least I'd not call it that.
I could just as well run random regulars and collect gear from those. The content is so low that whether I'm wearing triumph gear or frost gear, or 200 level blues, or lower, it's not going to be very hard. Sure, the ICC heroics require some gear and HoR isn't a mindless AoE-fest, but they're hardly comparable to even the challenge of Naxx.
10 man raiding will finally get somewhere. Can 5-mans get somewhere too?
