That... has very little to do with the particular timing of raid buffs (to per 2 minutes or otherwise) and almost everything to do with the likes of Communio and especially Hyosho Ranryu just having absurdly high effective potency for a single Crit/DHit roll.
Our nukes are excessively dense. That's not a 2-minute meta issue though.
This, likewise, has far more to do with there being little uptime optimizations and fewer contextual-rotational optimizations to be done in a given fight, not the 2-minute meta unless the difference in skill expression available between Stormblood and Endwalker were solely in how well one banked resources (most of which one couldn't bank anyways back in Stormblood) for minor/off-sync raid buffs (i.e., any raid buff which did not create or add to any of the highest density periods of effective damage amplification).When you can do a 75th per tier rotation and get a 90 because of crit luck in the burst window then something is wrong with the balance design
It'd be a lot easier to solve issues like these... if we didn't conflate them to high hell.
We lack for contextual skill expression, largely due to excessive fight simplifications. That's an independent issue from the "2-minute meta" though.
The maximally amped crit skill can cover that much potency, sure, but that's not the difference of the crit itself -- you're measuring the effective potency of the entire action there (and likely also failing to account for actual effective potency --as per damage traits-- of what you're comparing it against).In the current two minute meta a crit during the burst window of a DPS 1300 potency skill (so enkindle or hyosho ranryu) completely covers a healer never touching their dot in the entire fight. This level of variance would also cover approx 9 broken combos or 2 completely missed stardiver potency oGCD’s
Each Dia is worth 526.5 effective potency. The crit on a Hyosho Ranryu is worth some 676-1014 potency depending on one's Crit stat (+40 to +60% for those numbers). That crit covers less than 1 minute of healer DoT usage, not "the entire fight."
That is still way too much, imo, but... it's nowhere close to what you're saying. "Upwards of 38.5 seconds" =/= "the entire fight".
