I think if you want to gear up fast in WOD, you should consider doing group runs.
problem with personal loot in regular dungeons and heroic versions:
- forcing personal loot will cause the loot to be divided awkwardly, 1 guys decked after 1 day of farm in a guild run, the healer lacks 6 items including 2 trinkets.
- Having the option to change to personal loot won't work, situation A: 1 guy gets party leader, doesn't change to personal loot because he is doing this with 2 friends helping their members win items, situation B: same group with vote, you will lose as they are 3 voting no, while you and maybe the 5th vote yes.
to fix this you need to trust in the wow playerbase, which is a hopeless case at best, in most pugs people will need for items they want for offspec without any consideration that another player need it for mainspec, not because they're ninja looters, but because they wanted the item for they're other spec and mainspec/offspec is often equal to many players.
It's hard to change the mind of a 10 year veteran player that has done this since vanilla, to do it differently. I don't want to use the word stupid, but in this case it's valid, there is a lot of stupid players out there, who don't think about the consequences of their actions. For many the item hunt is the most fun part of the game, if someone comes a long and rips it out of your hand (like hunters needing on str trinket for ilvls or warriors for agi once for the same reason) it hurts.
Nowdays I've probably got 100k looted blue and epic quality items on this char alone, so items are no longer of that meaning for me, but in my early years of the one of the things that brought me into raiding was the thought of looking as bad ass as those veteran players roaming the field with mc/bwl quality loot.
That's my take on it at least.
