I am getting irritated with Summoner in endgame content

Same story with Titan egis. You will not have a chance to apply your full DoTs before I have flared them twice (including Titan) and lined up my 3rd flare for the finisher.

I use RS and drop dots on titan right after he comes down from heart. OT moves the egis, I give them a second for hate and slap bane.

Also for your parsing it doesn't look like you're adding the SMN and Garuda together. Also just as there are bad BLM, there are also bad SMNs.
