My advice is to pick 3-4 teams that work well, use each of them once in the first 3-4 nodes so they have turn meter then run your A team for the rest, swapping in a fresh team with turn meter whenever needed.
I'm level 85 so while this is not particularly helpful for you, what I do is I have an empire/sith team which works great vs Jedi, so I charge them up in node 1.
Then I charge a straight DPS phasma lead team in node 2
A rebel wiggs team in node 3
Then in node 4 I use my droid team and keep using them until they are either dead or I run into a team that is much better handled by one of the previous teams.
And finally I keep my arena team in reserve Incase I get into a real jam.
Again I know this is not something you can exactly do but I think the philosophy should still work for you.
