To me it means that I never evolve talismen because I keep thinking that I'll need to save those precious T1 evo runes for "better" ones that I "might" get.
Any T1 I get is going to stay as a 1* unless its gold or red, and even then its a maybe.
Either the drop rate needs to be massively increased (current evo dungeon has not increased it by enough), or they need to remove the T1 requirement from T2 and T3 2* evos.
