I’d say to people that think Val isn’t viable here to have a go with her, take health regen perk, concentrate on staying at range and tranqing as much as possible between heals. The monster will come after you, try to run more than jetpack. It’s no good boosting three times only for the monster to then be on you. Ask the support to cloak and use the chaos the monster will have to run through to get distance again. Only dodge if necessary, or for a first movement. See what you think after playing it more that way.
With Caira you are on a team that is trying to stay alive long enough to deal the necessary damage, with a Val on your team you are a team that is trying to focus damage at the right time to force the monster in to not wanting to be in the fight. Don’t take Val to try and outheal a monster, take her to put the monster in a position where the Assault doesn’t have to do a ton of chasing around in order to do it’s job.
Val is a medic who is all about positioning, and excels on a team where your fellow hunters are able to mitigate damage in the early stage of a fight. Most Val matches I see lost (where it’s not obvious the monster is leagues ahead of the hunter team!) I can categorise as being matches where the hunters have got stupid damage from wildlife and entered a fight requiring Val to expend all of her healing, instantly putting them all on the back foot, and reducing her ability to use her rifles to bring the utility to the game she should.
Edit: This isn’t to say I wouldn’t welcome very small buffs to Val, Lack of movespeed reduction while healing, a slight self heal when actively healing hunters, maybe even an innate passive higher movespeed… there are options there that could be considered that would take the edge off. I just don’t think she’s in all that much of a terrible spot as people make out.
