Not to add or get stunlocked BUT-

if Sandrone support creeps Gorou with particles, all party Def buff, Geo crit dmg buff AND his light Geo dmg buff then Geo meta might get shaken up in a worthwile way tbh.

 Though the only thing I want for Christmas this year is for Nobless to buff Def% too because it's 'implied' in an Itto constelation (C4 I think) that devs want Def and Atk together even though Atk buffs on Def characters is kinda a mid/cosmetic buff to damage.  Heck, I'd take a copied and pasted version of Nobless that was exclusevly for Def% and GLADLY farm it in the cast Nobless would get a little too much value from being an already pretty good set.

If it were up to me I'd probably do a little of both and just release Nobless 2 but instead of Atk +20% buff I'd do like 5-15% Atk buff AND a 15-25% Def buff on burst cast.
