Summoner's MP issues

[Niqote]

Edit:

I am editing out this part because either I cant make it clear this was pre- turn5 /usual smn damage rotation in other fights or people simply can not distinguish there are different parts to this conversation.
But i figured out my own rotation that works well in turn 5 so for that *points down*

Had another go at turn5 today. Basically I am just keeping the 4 DoTs on Twintania at all time as well as Shadowflare, once the conflag comes up I bane onto it then fester and drain and ruinII till it is dead, on the final conflag I am finding all I have is Ruin II though. Got past that phase several times to the one where she begins to dive bomb us and pull up snakes

^^ yay progress.
