Going from 0 haste to 6652 gives you 2 ticks. I was trying to keep it just like EVERY haste breakpoint card has it set-up so there is less confusion, looks like I failed to do that. As far as mixing up 100% haste and 21.43% haste, I did not mix them up. Insanedruid said "SotF increase the number of "base" ticks and thus makes the extra ticks less useful...You only get 1 tick from WG (SoTF or not) at 6652". Maybe I read that wrong - but I doubt it.
The 13k haste breakpoint is not better than 20% mastery. I am sorry, but I have no idea where you are getting this info from - in fact mastery is even more important if you are a 25m raider. Maybe it was because you cleared heroic ToT and had 535 ilvl from the previous tiers BiS where the 13k haste breakpoint was attainable. However those of us down here who are not clearing heroic content weekly (the other 99% of players who read these forums) are putting together gear from Timeless Isle, LFR's and normal modes. Telling these people that 0 mastery is fine as long as you have 13k haste at 535 ilvl is misleading, and just plain wrong.
