Yes. In an uninterupted dummy fight starting at half tp with haste gear that doesnt exist normally and a full memespeed build war 'might' run out of tp.

Ill stand by my earlier statement :P

20 seconds off 30 is the same as your gcd going from 2.5 to 1.666667 seconds. Thats never happening unless you have mega speed boosts on par with greased lightning 4. Not a tank possibility. Memespeed gunbreaker in traditional content could only work late stage expac while ignoring raid buffs (bad comp) or or just bot caring about raid buffs like a solo dummy or 24man raid deal.

Wothout some major shakeup its just crit/dh competing and way back there det and Ss competing for the 3rd place"i cant meld more of ky 2 good stats on this item". With the exception of war where its competing with tenacity for that slot and might have a prayer. Its just a fight for 1st looser stat.
