You have upg 2.0 which will cost you XYZ and you have Epic 2.0 which will be a set of spirit stones for your grade A/tali/ferkhan/opaniel weapons.
I'm inclinated to let the people chose between :

upg 2.0 = they buy one permanent weapon etc
epic 2.0 = set of stones adjusted, but they're not permanent + a slight boost of weapon.
