spell speed was not changed, just the potency of Fire so still takes just as long to cast.
Brayflox hm i have always used and started off with Ice 3 as too often i peel agro off tanks even with quelling strikes.
So it was Ice 3> Fire 3> Fire 2 Fire 2> Fire 2> Flare>Swiftcast Convert> Flare> Mega Potion >Flare
The odd time if trash still survived ( we pull every enemy up to first boss) then instead of convert> flare i would transpose flare firstly
Summoners are great but come nowhere near aoe damage of blm's
Many threads are out there with actual dps numbers and such
