I heard quite a few people making various suggestions regarding the in game hero's. I'd like to suggest a solution that will make them more exciting and hopefully more engaging than the current iterations. I propose;
Give players the option to purchase special Armour once level 20 and level 60 are reached. This will add some extra utility and provide the player with a few customization options. I suspect this will increase player engagement with the story and siege tactics. I know my hero looks pretty darn lame in his boring chain mail undershirt and sword and shield.
I really feel this could be the beginning of a serious chance at customization with hopefully weapons and individual armour slots far in the foreseeable future. If you need some armour ideas... im ur man
