I think it would be cool if they added like enemy crit hit rate -5-10% to ochain. Heres the thing with the shields and the instruments they can add things that aren't game breaking but are worth while enough for ppl to want to upgrade the devs just need to get over this idea that they are overpowered because they are not. The only thing that comes close to being what they mentioned as 150 is aegis in just its mdt. Ppl forget that one stat (Ochains block rate would be the other) don't represent a true 150 shield that if it were to exist would be 150 in all its stats.
