ADDING NEW CLASS

I do believe they need a better heal in game for all classes like something that would reflect the regeneration of the supper soldier organs that help them heal faster in batter the more they kill the more they heal. in the lore. Honestly they need to take out the Contested heal off the Bulwark banner and probably have it as a flat heal across the board for all classes and factor more into the weapon perks so you can fine tune it like they have in the chain sword and bolter perks, when they have +% contested health per-kill i think it is. This plus a Apothecary , BUT only thin with bring out a dedicated healer - you will need to rework Bulwark then . cause no one will run the banner and they will need to change that perk again ... 
Honestly, (Playing a Bulwark Exclusively) 
I think they need to remove the contested health heal Perk altogether. I have said since this game came out . the Bulwark is not and Apothecary, let that class have the heals and swap out the heals for more armor in stead. like my previous response use the bulwark for what they are, an 'Over shield.' 
 
Bulwarks are not healers, we are our brothers Shields... 
This Has Perpetuate Some META for people expecting bulwarks to keep certain perks to make them a walking stem kits, this would be a wrong direction, expected to be a healer. But with the contested health as it is now there is a chance to be a self healer. i think they need to have more heal options away from the banner, or change it ALL-TO-GETHER; So that when you drop the banner your kills have a chance to give you more armor to make every one glow with the Emperors light and you huddle together, killing and everyone is just regenerating armor, every one gets the 5th armor PIP as long as the Banner is there and you are close enough.  As your armor gets depleted and goes down with damage; every kill regens that armor pip or partial one; as the Bulwark helps his Squad 'Become' a large Un-Relenting wall that the 'Nids crash against.

 ( I like the armor idea better as it more fits with the theme; with the shield of the emperor; the emperor light; and the armor is just a buffer for the health system as a whole, like the shield is a buffer for the bulwark and the bulwark shields his brothers. This only furthers that rolling theme.. )

PPS- cause other wise when the Apothecary does come out like they want. That one class will single handedly make the bulwark current META for walking stim pack obsolete and they will need to tweak this class AGAIN..  why not get rid of it now and help be a shield for when the Apothecary is ready to come out and be a true healer and not rely on contested chances.. ????
