So about the additional character skins. I looked at the description for the “commander packs”.
It’s actually written that you will ALWAYS get one skin (and have chance to also get one new taunt, so there is also unlockable taunts that we don’t know about when we look at the characters ’ taunts) from it.
Those “commander pack” are faction related (rogue commander pack, and so on) and will therefore give a skin (and maybe a taunt) from that faction.
From what I’ve seen, the faction of those commander pack doesn’t seem to be related to which character you were playing when leveling up your commander rank to 5-10 and so on. So you can for example level up at Orendi and get a Eldrid commander pack.
The skin inside can be for a character that you haven’t unlocked yet, as well.
It is to be noted that the faction loot pack that you can buy with ingame money (that aren’t commander pack, you unlock the possibility to buy them after enough commander ranks) have a CHANCE to give you a skin and/or taunt for that faction as well.
So it’s one guaranteed every 5 command rank + a chance in every faction loot pack bought.
