Remember when we got those events wherein we can upgrade certain materias to their "True" versions? FFXIV if not mistaken.

With the advent of increasing rainbow rates, it'll be easy to get multiple copies of the TMR of a 5* base unit. But even then, multiple copies of the same STMR are still difficult to obtain.

As a nod to whales who support this game and to those highly unlucky. I remember reading someone commenting how he got his 3rd Sieghart STMR from the 6 1 4 rainbow pulls.

What do you guys think would be a solid non meta breaking upgrade to STMs? How about a 10-20% upgrade for a certain stat/resists or even some flat stats for materias.

Sounds reasonable, no?

e.g. Elena STMR From 60% Atk/Mag and 50% TDH Atk/Mag

To 70% Atk/Mag and 50% TDH Atk/Mag

Not too game breaking for the price of 4-8 copies of the same unit and 1-4 copies of 50% STM moogles, would you agree?
