Suggest to the devs to make the 12-win arena exclusive skins from previous seasons obtainable.
For example, as of current, if you get 12 win first time, you obtain the current season skin of “Old Ways Ulfar“. Then the next time you get 12 win, it should give you a missing skin from previous seasons (i.e., “Spectral Ner’Zhul“ as of now). And then giving the 2 golden pack after you have all 12-win arena-exclusive skins.
It seems the devs are planning to rotate to a new 12-win skin every expansion. It is really hard for any one to keep getting a 12-win within every expansion window (~4 months), given how hard it is to get 12 wins and how competitive the underground arena is.
I really wish the devs can consider making this possible so that these 12-win skins are not time gated to a very short period and there is no way to guarantee obtaining it within the time window.
