I think one of the issues is they don't test play their games, or they are bad at it and therefore think Fireteam needs buffs to win but in reality they aren't skilled enough to understand how a skilled Fireteam can really wipe Predator blood off the face of the map. I remember one of the devs on twitter mentioning that they haven't even played Predator in a while so that was kind of alarming. I need to look for that one but that isn't a good sign if this is the case.
One thing that would help greatly is if Predators also have class specializations. If you go to each of the species loadout options, they have "default" under each slot, with Fireteam obviously having their specialization options. Predators don't but it seems like the option to add one in the future is there. I hope thats the case cuz it would help make the classes very diverse in gameplay as well.
