I am getting irritated with Summoner in endgame content

[Madoka]

swiftcast is not optional

in a some aoe situations like turn 4 and titan ex summoner aoe damage is aces. I put up RS and bane on the first set of soldiers on turn 4 and they melt. no blm can do that

I save my RS for the 2nd dreadnaught. That + int potion, shadow flare, contagion and a fester and then I switch over to the soldier that spawns with it while I still have those buffs and slap dots on it. Our BLM usually doesn't attack that soldier for some reason but I still get it down while doing a shitload of damage to the dreadnaught.
