I finished the Event Objectives with 3 of my accounts only on Monday/Tuesday, but keep active in the Bonus Crates only my baby base Imperial HQ 6. Not funny have to earn 900s ep and all these units don't worth 6-7 attacks against big HQs 10... Only 1 Bonus Crate for my Imperial HQ 10, and 3 Bonus Crates for my Rebel HQ 10.
As the only old Elitte not maxed out for my Rebel HQ 10 is AT-RT, I stopped when saw most rewards were for more "Death Chickens" frags, AT-DT, SD-K4 and the Demolition Droid, more Senator Leia and Tauntans... No thanks.
As my baby Imperial HQ 6 is a new account, anything is good, and 5 attacks 3 stars in less than 10min for 5 rewards at each 2h, it's great. Think I got about 16-17 Bonus Crates, and Hauler and Tie Brute unlocked only with frags in the Bonus Crates. Everything else's upgrading to level 2 or 3 now.
