I'm going to have to diasagree, if you got Rey/ SLKR (what 2/3 years ago?) then you've benefitted from her in Raids, TBs and Conquest etc so the payback is quite high in terms of crystals and rewards in game. I left Rey behind as each new GL got released, I chased the new ones - I was always a year behind and that suited me to benefit from the accelerated drop rates for toons. Rey just never interested me until today - for $20 I went from 4/14 to 12/14 toons and only need to R7 Rey scav and BB8 - one week max and I'm farming LS tix for Rey and 7/8 GLs done.
So thank you GL - we'll forgive your errors of judgment in conquest...well maybe
