DK fastest possible flying?

Will 310% flying stack w/ pale horse and the guild +10% mount speed bonus? And What %boost will the end result be?
I think so.
Nex is correct. Pale horse doesn't stack with other movement buffs, says so in the talent.
whats the total end result speed though? 330% or 372%?
100% (walking speed) + 310% (max flight speed) = 410% + 20% (OaPH) = 492%
392% w/ on a pale horse if you have a 310 mount.
It's 492%.
most people don't add in 100% run speed since it's a given. you'll see 392 constantly posted everywhere as it's in terms of how much extra your mount is making you move.
Press C and look at your "general" stats while flying and it shows your speed
310%+Pale Horse= 492% which ties them with Paladins for the fastest thing in the skies of Azeroth.
492% flight speed with on a pale horse. No other speed buff stacks with it.
495%, just like paladins.
