yeah, i spent about 2k in great plates to get kakashi, i ended up getting about 400 power out of it. the only power i could get was from grasps. thing is those r the best way for me to get power atm, so the fact that 2k in plates only gave me 400 power instead of the 1k power i would have gotten just buying grasps is why i say its not good. i cant use medium refines anymore so there is literaly only 1 item to give me power in that event and when you get to my point in this game and you have over 900 medium refines sitting in your inventory you realize you shouldn't have tried to get so many of them.

bought 200 dice(4k cp) for LB today and i got about 2500 power from buying grasps and the free items, much better event for power for everyone than great plates
