Do the Collection quests that have good drop rates, avoid those with poor drop rates(Goretusk Liver Pie, Southshore Murloc Heads, etc)

I twin-box and so far as /played time goes I'm average for my playstyle, not ahead or behind of my usual solo time. As far as quest progress goes though I'm zones ahead of where I'm usually at. Pre-2.3 I'd be scraping for exp and quests to hit the next "threshold"(Such as clearing duskwood to barely hit 30 to start STV, and having to do most of those quests before I could move to arathi); post-2.3 at lv41.5 I've barely touched wetlands, done maybe 4 or 5 STV quests, not run SM but twice for Library boss weapons(and no quests from SM to boot) and basically have dozens upon dozens of quests to still go through.

Yeah, the patch made some niiiiiiiiice exp changes. And there's also the new Dustwallow marsh, which took me from 36ish to 39 in a single afternoon of play, highly recommended to go there once you can handle it
