I agree it's less effective for those and other reasons vulture, however the math shows beyond any doubt the dps is highest with all gear evenly spread out.
out of curiosity would you mind posting the math here?
I fear I'd bore people with the math so I'll give the tl;dr. All skills from focus str or dex and auto damage from str scale as the square root. Direct add like elemental and direct add to skills don't. Set bonuses complicate this a bit, but there are too few to tip the balance and matter overall.
Most people are too lazy to hotbar so if gear is spread out its much more likely to be equipped than sit idol for no dps.
The optimal solution is to use all the gear but minimize str, focus and dex gear among the respective toons who use it. Complete sets without disturbing this as much as possible. Elemental and direct add can go on anyone.
That's only the math of it, it's true giving out DG gloves is more dps than DG sets even. There is already a thread on this. However the problem is not simple math as many have said.
When you have highly active people who always show and casuals who show maybe 20% at best it's not going to be optimal to spread gear evenly.
When you are locking bosses diffusing your gear is not going to get you a lock. Basketball teams need to win locks, if you wanted the most baskets you would put all spectators into games and get thousands more than a few pros could do. But you obviously won't win against a pro team.
When you distribute gear and have an inequality in work done to reward given its going to cause motivation issues and dissent.
When it's on people who can't work together and can't implement strategy it's not going to be as effective as if it's on competent people.
If you have the best gear on loyal clanmates who log for nearly every raid it can get you can kill bosses without help from more people netting you more drops.
Etc etc etc. However it's pretty clear that in the most general sense diffusing your gear provides the most dps.
