Summoner tips?

[Squishes]

I don't want to activate Aetherflow in advance because you are full MP at the start? I use it as a mana restore, and Energy drain to keep my mana in check. Why would I want to activate it when my Mp is full and it does not boost my dams at all?

You want to use Aetherflow before the fight because it lets you start with 3 stacks and the cd on it already running or already done so you can get more Festers in within the first minute than you would get if you didn't start with the stacks already up.
