I thought that 90/90 characters had enough stats to equip absolutely everything in the game. That is with 0 skillpoints invested, unequipped mag and 0 stat bonuses from levelling classes to 75.

On topic: I felt this was a missed opportunity, given that ET seems to be defense-oriented, to have its mag also be focused on the defensive stats, and have many of its support abilities scale with defenses as well (for example larger cooldown on abilities based on DEF, i-frames scaling with DEF, etc.)
