After having just got done playing the most amount of Predator matches in one night than I have in several days, I've got to say.....
*dramatic pause*
.....I think this is overall a good patch!
After the first few days of playing mostly all Predator matches I got pretty frustrated by a lot of the balance issues to the point where it just felt like playing as the Predator wasn't nearly as fun as it should have been. But thankfully I've got to say that by and large these changes do seem to have addressed the balance in a positive way.
I went back and played Hunter and Scout after having mostly stuck to Berserker since I unlocked him, and at least as far as the Hunter is concerned he definitely feels like arguably the best class now. Scout unfortunately still doesn't seem to be too viable, in part because of the nerf to the plasma caster taking away one of its main long-range tools, but the addition of one extra gear item is good, at least. I just wish the smart disc was better too so you could go "full long-range", but it seems like he still needs a melee weapon of some sort for those claims.
As for the Hunter though, he felt great. The increased number of pigs/boar and the ability to track them via target scan is great, since it still has that random edge to it (I only actually healed that way once, maybe twice), but at least now you don't end up using almost all your heals in order to kill and claim people only for them to be reinforced back in and reset all your hard work.
He can also take enough damage to make it so that you don't necessarily have to heal up every time you jump in to melee or claim which helps with that, but he's still squishy enough that two or three fire team members blasting at him will melt him super quick. I played a fire team match with a Hunter who tried to combistick rush right at the start and he got one claim off before we put him into second wind and he ran off for a bit before detonating himself, so that's definitely something you can deal with so long as you're not split up.
Overall it just felt like I was able to do what I've been trying to do since the get-go a lot more now as the Predator and not be punished as much for it. The added reinforcement time only seems to be a few seconds or so and it really doesn't make a big difference, but given that if you play smartly and get a bit lucky you shouldn't have used up as many heals by the time they're brought in now, so it's less frustrating to deal with.
I also wasn't getting parry/knife spammed at all either, which makes me think the stamina changes are doing their job.
There's still some obvious jank and issues they need to fix, but I'd definitely recommend giving the Predator a go again if you're anything like me and decided to take a break out of sheer frustration.
