Erm... CT had 0 tolerance mechanics? King Behemoth'd be prolly the toughest fight there but the reason people wiped is because you have clueless monkeys running around, not knowing what to do and new tanks who can't tank the Iron Giant properly, despite having more than ample time to react to it. Things like landslide gives you shorter response time and Titan EX requires more situational awareness than CT.
And that's why CT gives i80, not i90.
Anyways, nope. I'm not signing up for your so called "SE stop using 0 tolerance mechanics" so that more people do coil and get the highest tier gears.
Maybe SE could do something like 2.1, introducing i110 accessories (only accessories) drops from EX primals (Ramuh maybe?) but of course, should pose similar difficulty as Coil 2 turns. I welcome a variety of choice but the difficult of the fight must match the ilvl of the gear offered.
Left-hand-side body pieces which offers VIT and defensive stat upgrades should probably still be gated behind Coil. I'd agree that the current situation is a little annoying with everything gated that's why I welcome a difficult Ramuh fight in 2.3 that would drop i110 accessories for a variety.
BUT! At least right now I can tell who can handle 0 tolerance mechanics and have the discipline and who do not. Simply because currently, Turn 7 is a huge discipline check. If I see you have T7 drops it means you passed T7 and you have the discipline. If you had a T8 drop it means you have both the discipline, and the required understanding of your class to pass the required DPS check on Turn 8.
If you do not possess these qualities, you can be contented with Soldier gears and upcoming CT2 choices. Although having better gears does indeed make things easier to roll due to higher damage and higher HP whatever, but that's because you and your raid already knows what to do, had the skill and discipline to do it. Just look around and you'll see players decked in i90 myth gears with a mix of i100 soldiery in T5 who can't even dodge divebombs and twister properly and wiping despite 15% echo buff. Does gear help these people? Nope, not really. If you can't handle low tolerance mechanics, i1000 gear doesn't help because you will still get one-shot by that mechanic.
