First LOL run. Any input highly appreciated.

Hey y’all, I’ve been thinking about giving LOL a try but I’m not sure where I stand. I’ve explored both Variant 2&3 and currently stuck on 6.2 with the final section(Champion). Should I go for 6.2 completion or 1st run on LOL? Also, I have no revives or pots in stock, am I looking at a heap of unit usage or??? This is my roster so far. Any input would help...
