I don't expect a level of customisation to rival Fallout 4 but I would like to change the colour of my Berserker's beard, for example, and hopefully a larger variety of armour pieces. I assume the lack of different armour is due to this being a testing stage and not the full game, so I will let it go. Also, it would be nice to be able to choose our own colours and not preset groups.
Other than that, the way the customisation menus are set out work well apart from loading into the Heroes menu isn't very smooth and the Emotes menu won't open.
