Predator needs more heals

In long matches where pred claims a couple kills and fireteam has basically unlimited heals, my predator many times has to chase down full fire team (because they reinforce) with full health, while predator has 2%. So when that happens I can’t really engage

I don’t think too many heals is necessary for a predator. I prefer to play as predator, it is fun. But, you need to know how to widdle down and engage your enemy. Force them to use up their resources and harass them over time while they try to complete their objectives.
You can one shot people with the shoulder cannon hope you know. That should be one of your main weapons to use in the beginning anyway. Unless you do see a straggler that you can pluck from their team with some melee.

You can’t just blitz up in enemy faces unless you know what you’re capable of. That’s how you get melted.

So, yeah my advice is to harass and hit them from afar before you go in harder to take them out.

I get it though, the reviving of their dead teammates is really annoying though, especially when they can revive almost immediately upon you killing someone. That’s one thing that I swear does need to be changed severely.

If you want at least one more heal though, use that pouches perk, or use that perk where your second wind passive has a quicker cool down as that ability has infinite uses basically as long as it has cool downed to use again.

One thing I like to do that almost immediately always takes someone out of the fight is to go somewhere where I know they will have to go to complete an objective before they get there, place some bear traps down where you know there will be avenues of approach relative to where you may be perched, and just wait for them to walk into a bear trap, it’s like shooting fish in a barrel.
If you down someone, don’t immediately go for the trophy kill or finishing them off. Let them bleed out and have them call for help for someone to pick them back up. Once more of their teammates are near to pick up the guy you downed, then that’s another easy kill.
I like to use their own teammates as bait to kill the rest of them.

For stuff like that though. I would suggest using the Down range perk for stronger range attacks, I use the dithed lense as well, although you really don’t have to, they can still see the laser from the shoulder cannon sometimes. But that fully charged shot from the shoulder cannon is what obliterates people in one shot usually.
It’s literally the strongest weapon out of all the predators arsenal.
Good stealthy vantage points are also great if you can find any.
