Gearing up for raiding has always been an important part of an MMO endgame in my book. If this process is replaced by real money-bought gear...
This process was killed by LFR already. Currently:
1) Hit L100
2) Go to AH, buy some random green/blue shit to bump your iLevel to whatever's acceptable for heroics (or, if lucky, LFR)
3) Do heroics til iLevel is acceptable for LFR, usually 3-4 runs. Then move on to LFR.
Voila! RIP, gearing for raids.
Fun fact: Despite this ease, many people still manage to fail at it.
