I have a few days of sub time left and am trying to hit 80 while completing as many zones as possible (given they all give a +1 power multiplier).
I then plan to take off for a month or two and come back when all the content is released (along with many of the power multipliers) and gear isn’t capped so low.
I just don’t see a point playing this mode at level cap as gated as it is currently.
