How huge is the difference between 6*/7* Thrawn.

I'd still like to see someone beat the Tier VI of Thrawn with a level 70 team since the recommended level in the event is "70+". Same as for the R2 and CLS events, they don't seem to know what "recommended" means.

Thanks for the input though, good to keep those things in mind for when I do it. Mine are all 7*, but in the high 70s. Hopefully there's a credit heist before this event is over so I can at least 6* unlock, if not 7.
