Sorry bit far back raided after posting comment and went straight to sleep after, yea i'm under no delusion of past raids some felt good to clear and some were just awful, no raid tier has been immune to issues. Midas's A7S beam +DoT tick could kill someone before you could react due to server ticks lets also not forget the buggy mess of A6S where your could straight up wipe for no fault of the players, phase pushing of Creator was a problem. Delta's glorious Alte Rolte who was easier than extreme Susano on their respective launches, Sigma's Gaurdian who my group firmly believe Kefka pilots due to it randomly start targeting a tank for beam before doing a complete 180* turn killing every non tank as it fired, Alphascape's Middy who no one seems to like as a savage fight to the length of A12S.
Currently a big problem I have with savage fights(some Exs too) is the random Enrage timer, some pulls get longer some get shorter due to whatever pattern the boss decides to do (It has been an issue since Gordias Jigglybutt was the 1st time i really noticed it), i think this should stop period, they should have a set time only and the boss stops casting/doing its pattern the moment its enrage timer has gone over and wipes the group.
Ah i remember this my group was part of the 38k A2S people, we were both happy and worried seeing that number, it felt like we were part of a small club but at the same time it worried us that if anyone was unable to make it we were unlikely to find pugs to replace and this drove morale down hard both looking at A3S/A4S clear rates due to our 2 day a week/3 hrs per day schedule, we eventually got A3S down in patch 3.1 and we tried A4S but ultimately decided not to bother as we felt we weren't going to kill it before patch 3.2 launched.
What also didn't help Gordias was that the weapon was ilv 210 which was equal to the upgraded tomestone weapon/relic weapon at the time so the only real incentives for A4S was BiS and a mount.
