Hunters up to top of list and on the dmg done and everything not even close someone needs to fix their charts of bull. So Dumb anyone that pays attention to these are dumb also.
An easy fix for Arms would be to revert In For The Kill from lasting the full debuff duration, back down to 10 seconds... This means Arms Warriors can't get upwards of 50% uptime on a +20% Haste buff during the execution phase on a Boss... Instead it would drop to a much more sedate 30%-35%, whilst not simultaneously gutting the whole tree... At the moment, (if you so chose) you could take Spiteful Serenity along with Blunt Instruments and get a 23, yes that's TWENTY-THREE second Haste buff of +10% during the first 65% of a Bossfight, or +20% during the execution phase...Also, that's not much of a pool of Mythic raiders... <40,000...
