Even if it's 25000 thousand glimmer. I have three caracters that would've maxed out this limit 3 times if I really wanted them to. Glimmer AND something else (idk maybe ascendant energy since everybody has too many. I have 13 lying in my vault and nothing to upgrade. One of my friend even has more than 80) so that way it's harder to fully upgrade because you need more energy, but you don't need a commendation.
