I think that different skins should be added to all teams, at least one in each. After all it has been a long time since any skins are modified in any team so a change should be implemented.
The skins above are unused and not popular by vips as I observed. Give regulars a little more
That doesn't matter so far as some of the skins are said to be reserved for each class even though VIPs can wear other team's skin while being in a different team.
