I would say temporarily shelve the team.

And level additional teams from 1st to 60th.
You have the RAF now.
And 1-60th will be much faster now then later.
The 60-80 will be the same time now or later.

You can boost 4 toons from 1st to 60th, with a semi geared 5th toon in under a week.
Or with 5 toons all leveling together, it should not take you 2 weeks per team.

Having multiple teams at 60th is good...
You can level one group for a while, and then another.
And level up with rested the whole way.

One composition is different from another.
So it keeps the game a lot fresher.
A melee team plays a lot different then a caster team.
A mixed team is different from either.

More toons will get you more granted levels as well.
Even if you're not set on having several sets now.
It will open up doors to you later, when you'd like to try another combination.
Or perhaps add a <insert class> to your existing team.

Once RAF is over, I'd level to 80th, over gear at 60th.
There's likely nothing at 60th, you'd be wearing at 70th.
And nothing from level 70 that is worth having at 80th.
Aside from putting in the bank and remembering how hard something was to get.
Nostalgia is about the only value the level 60 stuff has.
