As to haste vs mastery, in the range you are sitting (>8.1k and <14.8k) the only points where I would expect haste value to spike is before the HoG tick threshold at ~9.3k haste (Endless afflictions). For the fights you have remaining, full on haste would be of potential benefit for both Council, and Animus - especially if you can break 14.8k by them
. Everything else, lower haste with more mastery should be better overall, as they all include some aoe heavy point, which beats out 0.5% dps you might gain on singletarget.
