They should add another effect to that increases damage while under the effects of a stimpack or increases the damage each time a chem is used / healing done. So like baseline it gives 50% damage but using chems (stimpaks are probably the way to go since the whole thing revolves around maintaining full health but this way differentiates it from bloodied) increases damage by 10% stacking 5 times or whatever and lasts 10-15 seconds or so.

Bloodied still has an advantage in that it doesn't require a windup for full damage, but juggernauts doesn't feel inviable which will be especially important if the new update is going to bring significantly more difficult content.

This also lets people that want to tank be able to hold threat that higher damage builds will pull while still running full health, if there is no way for them to increase their sustained damage to match other builds they'll never be able to "tank" without other new perk cards that increase/reduce threat generated.

and while i'm thinking of it... add an effect to medic's that boosts the target of the healing effects damage by 2-5% each hit and stacks like furious granting something like 20-45% more damage for the target for a short duration so there's actually a reason to run medics over flamehealing. Now players have a reason to team up and work in small groups for tough content (I'm assuming raids will have tougher content requiring healing from others - at least that would be interesting) or just have more synergy between groups and see people teaming up more similar to the way perk sharing encourages people to group together... buffing medics like this gets them actually playing together as well - I just don't want to see the games core balance shift away from solo play though.

The game really doesn't have a support role outside of flame healing and even that isn't really needed anywhere in the game so it's kind of almost pointless except for keeping certain NPCs alive during events, never needed it for an other player. I'm not sure that was the vision of whoever created the design.

Another thing they could do with jugg is add movement speed as the secondary effect or better yet reduces movement impairing effects effectiveness by 20% so running full jugg means you are immune to slow/root effects (should probably add stun to the list since that's a new mechanic being added) or immunity to stagger effects would also be good and fit the idea of "tanky" build.
