Low level isnt limiting or a disadvantage. I recently started my eldar again after EA so i was rank 1. Played 3 games and was top player. You gather XP wit your experience and knowledge about situations and weapons, not with shiny guns.
Love how everyone's jumping on the grind when the main complaint is the shared progression, even the title says so.
Soon™ you'll be able to change your characters sub faction. This solves the issue for anyone who wants to switch sub-faction but doesn't want to level a new character.
why would you even make multiple characters of the same faction though. Just pick your favorite color the first time.
I would just like to point out that there is 4 characters slots. And there is 4 races. Did you seriously wasted one just for a change of colour of your LSM ? Because actually there is not that much customisation difference (eexcept for Orks) that is worth creating twice the same race. Also I remembered a post long ago that asked if it was possible by contacting the support to change your subfaction, and they did change it.
I think you might have missed the point of the OP. I'm not complaining about the fact that you have to level up a character. I'm saying you shouldn't have to do it for each character in a sub faction because they're identical.
A new character of the same sub faction that has already progressed substantially. I already explained why.
