Wow, just Wow!! This is a mess though isn't it?!
Everyone gets 250 crystals is the only thing that is clear.
Those who had a 7* Malak prior to the release of the 3rd appearance of the event also get 2250 shard shop currency; you earned it already, you earned half and will get the other half, you didn't get any and so you will be given 2250. That is also clear despite the fact people like Kyno keep disputing it. What isn't clear is why do those of us who had the 7 star Malak only get this reward?
Those who don't have the requirements to attempt the event are also thankfully easily sorted!! However, In the middle it just gets to be a mess. Someone had 70/100 shards; does one half and gets 75 shards. That is a 7 star Malak and 45 shards to be converted to shard shop currency. How exactly does this player get dealt with? After the fix they will once again be at 70/100? Okay, but now what about the shard shop currency - do they keep it? Is that also taken from them? How can it be. Maybe is has already been spent to gear Malak, or some other toon, or just in their inventory. My head hurts thinking of all the permutations out there. I kind of feel sorry for CG.
In all honesty, I know this will sound greedy on my part - but the simplest solution is to look at where everyone's Malak was at prior to the start of the 3rd release. If you had 7 star Malak, you get 57000 get. If you had a 6 star Malak at 70/100 you get 120 shards worth of GET. If you were at 5 star Malak at 10/85, you Malak is bumped to 6 stars and 75/100 for shards. People who unlocked or brought him to 7 stars and then spent money can never be properly compensated can they?
Best of luck to you CG in sorting this out, but honestly your initial communication for your plan is not a good solution. My solution will appease most everyone and hey, it will help you keep your promise of alleviating the gear crunch too. Also, don't forget 250 crystals and 2250 shard shop currency for everyone in addition to the GET payout based on Malak's status 10/18.
Live long and prosper, err I mean May the force be with you CG.
