You're delaying upheaval by FOUR gcds. That's 10 seconds on a 30 second skill. You keep talking about how delaying things wont make you miss another cast of something. Delaying a skill by 33% its CD has a large chance of missing a use before a boss jump or end of the fight. There are many fights right bow that 10 seconds would make you miss that upheaval and some that would make you miss an entire IR window delaying these things by 10 seconds. Eden 1, miss ir. Eden 2, no boss jumps, but still increases the odds of missing upheaval by 33% and it by ~10% depending on rng of your parties kill time. Eden 3, I'd need to double check, but I think you loose an upheaval here too. Eden 4.....good god this is horrible. You will straight up loose an entire IR window before the long transformation phase along with everyone else using 90 sec buffs that waiting for this thing. Just mind bogglingly bad here.

This is not practical for any fight on war in savage. E3s would be the 'least' bad, but even then you may loose an upheaval.

This is all just horribly impractical.
