There's one mechanic you seem loathe to admit isn't possible to skip in T2, due to what is obviously a personal bias: the buffs. You still have to pick the right nodes to take to ensure you don't earn any buffs that complicate the fight. I've seen parties wipe T2 because they have 3 casters and instead of picking the safer route that would add the entirely harmless Blunt Resistance buff they kill the Disposal Node and add Magic Resistance. Ergo, they lowered their DPS extremely and could no longer pass the check. Additionally, T2 enrage is a method that STILL requires a lot from healers (if you think it's just "spamming" abilities, you're wrong) and again, I've seen wipes due to singular tiny mistakes. It's pretty clear your argument stems from a personal bias that amounts to "I don't like T2 enrage, therefore it's bad" regardless of the actual realities. As was said, about the only reason to go for Rot is it is slightly shorter, due to not waiting 6-7 minutes having a tea party.
