Until someone shows me a link where everyone in the raid won something I will be extremely skeptical on how someone else's roll effects others. But as far as I am concerned the afker in the corner winning something and me not winning something is the exact same as his winning causing me to lose. Its the exact same result. Whats changed, we can't see it, thats it. Results are all I care about.
As for DS, I geared up three alts through DS lfr in about 3 months. I might have won 5 useful pieces through all my toons combined since mop. Though to be fair I don't run lfr often and as a result my alts are poorly geared.
As a final note, I am a fan of RNG. When you win you get excited. Problem is you still have lots of RNG but its almost immediately soured when you "win", if it can even be called that, an item you don't need. So either they up the "winning" chance or give you more control of what you win.
My System
Ivy Bridge 3570k OC 4.0
ASRock Z77 Extreme4
Saphire 290
Mushkin Enhanced Blackline Frostbyte DDR3 1600 8GB
Dat loot QQ <3
I expect in the next expansion they will allow us to spend charms for a chance at a specific item, or have a thumbs up/thumbs down loot table that will allow the game to more accurately fill our needs with the same or similar RNG system.
Until then the CM's will do their job by defending the systems as an alternative to saying "You're right, it's not great, and we'll have it fixed within a year. "Soon ™"
Getting repeats isn't RNG, it's dumb. At least before you could choose to pass on crap. Imho, the loot systems are fine, but allow trading of gear we win in LFR to players that shared the kill. Or at least exclude an item we already have if it's going to give us something. Most of the time the item that's a repeat is less vendor gold than winning the bag....
It's not even "artificial", these systems are designed around gambling and reward theory. This is the most addictive and ultimately psychologically rewarding system that offers a "high" or rush from winning, and you act like it's some sinister plan to trick you into spending time. This is what happens when people burn out. They forget that you just play the game because it's fun, and start seeing that what you once found fun isn't fun the 100,1000th time you doti, and you recognize you were just addicted to an artificially designed system of reward vs failure. Once that appreciation for the rewards vanishes, you burn out and then start blaming anything you can but the actual truth.
