Going to be honest I'd quite happily see Enrsge timers gone. All they do is make things a mandatory speed run.

and it would be an relatively easy thing to do. if you want to limit deaths and stuff in content without enrages. easy bring back a death penalty. enough deaths and your tema starts dropping to 69 and basically have no chance of finishing.

alternatively add more individual dps checks. make susano ex do another massive sword drop on the arena. or do more of them in general. kind of thing. keep the requirement for dps there so ya know if you have 6 tanks and 2 heals you won't make it. if to many dps are dead you wont make it....

Things like this I really don't mind seeing. and would be fine if fights had more of them. especially when most fights typically only have 1. the things I generally hate are the great big screw you's that happen after like 9 minutes and 45 seconds or something when you've got the boss down to like 2% and just need 15-20 seconds to kill.

they could easily add more dps checks to content while scrapping total enrage timers and keep the content challenging / prevent zombying / 6tank setups...

someone above mentioned ifrits nails. that was more a dps check than an enrage. even in extreme from what I remember. as long as you killed the nails every time. and passed each dps check you could practically take as long as you needed with the rest of the fight. in a way I think more fights should be designed like that. more frequent dps checks in place of enrages.

tune the individual checks a bit tighter and add more of them but scrap the enrage timers...

rabanastres first boss for example has dps checks but they're ridiculous. half the alliance can be dead and still clear the dps check. I think that's a real problem that needs to be addressed. same is true in a lot of other content. enrages could easily be scrapped if those checks were tuned up a bit and occurred more often.
