After the patch, I was very frustrated to find out my lvl 20 vincent legacy insignia could no longer limit break. If I can't MLB it anymore, I consider it trash and just a waste of 2 5* vincent, not to mention the upgrade cost.
I was scrambling to MLB my second vincent insignia before the time limit, but I came up short with about 20 keys to promote my last vincent to 5*, because Devs geniusly or deviously scheduled the maintenance at 5 a.m. I would have attained sufficient amount of relics with thursday's key recharge which was within my calculation. I was tempted to recharge keys when I found out the maintenance was scheduled for 5 a.m., but that would mean I would have to spend about 500 gems just to reach the required amount of relics. Caused me all sorts of inconvenience as I was hoarding equip materials to MLB that insignia and filled my inventory to full capacity and just to find out I will have to use all those for unintended purposes.
I strongly suggest you translate as Legacy only the MLB insignia preupdate, and all non-MLB insignia to remain as normal insignia so we can still LB it to maximum. This is completely outrageous.
