One of the other fishermen whispered me and said that the time wasted traveling vs fishing when you share a pool slows you down.
I replied that sharing a pool is better than no pool.
We discussed it briefly, he mentioned that it's true for the Stranglethorn Tournament (someone did the math on El's) but perhaps not so much for the Kalu'ak (which is more random). Looking at the Kalu'ak page, El still recommends not sharing pools, though I don't know if there's any math attached.
My husband's best friend says that it doesn't matter if you arrive late to the Derby. As long as you arrive before someone else wins, you're still as much in the running as you would have been otherwise because of some weird "chance to catch goes up as contest goes on" thing.
One thing I do know is that Alliance has an advantage in a race to the turn-in. It's much closer to that side of Dalaran, and if Alliance and Horde hearth at the same time, the Alliance will win (unless their loading time is pure crap). It's not something Blizz thinks is a problem, but if you've ever lost by moments as Horde, you know it really is.
To help your hearth go faster, El says to set your graphics as low as possible except for Spell Detail. Also, Engineers can make X-Ray specs which make everyone nude, so you don't have to load anyone's gear.
Now, what do you think about all this? Practicality, ethics, tips.... have at it.
