If you are running away from a mob, it means your pants (or shield or whatever) won't proc causing damage to the mob and thus locking the encounter causing your run speed bonuses to drop and your health/power regens to slow. For me it's freaking annoying trying to just breeze pass a bunch of greens on a carpet just to have my pants fire off and lock the encounter.The healing issue is moot because it will still proc if you are running away while still engaged in the encounter. If you are running away with the encounter not locked, the natural health regen from being out-of-combat is high enough on its own unless of course you never bother carrying food with you. This is also for armor only so your reactive regen proc will still work.If anything, it makes it easier to just run through a bunch of aggro making this change a huge travel buff.The shields make sense, to me it's obvious they were way out of whack with what a buckler should be.
