the ITF is popular as it has an enemy group with mostly non-mez, simple damage types. all mobs are close together and there’s a lot of them to plough through
a lot of the TF is in spacious, open world maps too. the objectives are also simple and easy to understand
Aeon as a TF is best experienced on medium difficulty in my view
regarding your point on being left behind during speedruns - that’s a failure of the team, not of you. i have incan on my speed run alts and always bring everyone to the main objective. on iTrial speed runs, i’ll work with the team leads to ensure there’s always 1 person with incan ready to use, so we can move the league around where needed
