I have seen way too many predator mains get so frustrated that they can’t instantly melt a fireteam, when with the right combinations they can do just that.
I really suggest that you take the time to learn the game from both sides before you say that predator should be buffed (fixed is a different issue as those are bugs) and fireteam should be nerfed.
The best part about this game is that the fireteam has the firepower to knock back at the predator, this is not your dead by daylight game where we all cower in fear and have no way to fight back.
I have seen some amazing predators go up against some amazing groups and it is very close, tipping either way depending on who does what. So please take the time to learn both sides, not just only play predator or only play fireteam. This game is amazing right now (minus the previously mentioned bugs), and the fact that everyone and their mom wants to play predator which means that predators get less experience and learning then come to the forum demanding buffs to predators and nerfs to fireteam.
Please, take some time to learn each side and you will see that well-skilled predator can defeat a well-skilled fireteam, or the other way around; it becomes a close game.
