This strict 2min Buff windows lowers the skill ceiling but also increase the skill floor.
It is also just not fun because you mostly rely on big GCD crits in a short period of time.
Like, yes, big number's are nice and all, but not having this big number's multiple times in a row due to bad RNG feels just terrible and demotivating.
It is so bad that you not critting the potion burst can lead to a 0.1% wipe.
Terrible game design and I think the should get rid of most groupwide buffs.
