Multiple Abilities for Max Levels

For example when you hit a max level you could be granted another classes ability (maybe further accessible through equipping the correct armour/wargear etc). This would be like assigning them to a menu wheel. For example; you could hold down the ability button and select one using the d-pad or joystick etc etc.

Increasing the max level to say 50 could unlock more access to abilities tied in with equipping the correct armour. The new iron halo from Secret Level can only be worn by the Heavy but is of course attributed to a Bladeguard Veteran. Maybe we could unlock the wargear or armour pieces by reaching a higher level in order to use the abilities correlating to another classes armour or wargear. This would add to replayability to obtain these abilities as well as offered more than just aesthetic to the armouring hall.
