The amount of xp needed to max red glyphs/signets should be drastically reduced tbh. If the amount of xp needed to get a glyph or signet to red 20 was the same as it took to get a weapon to red 20 then it’d feel way less onerous to do multiple sets.
Levelling red glyphs and signets feels awful because getting a level takes forever and then you get like, an extra 0.01% gadget cooldown or something. It’s the same feeling of putting in effort for no reward that you get when you’re levelling a second yellow anything for fusion
