Exactly. I don’t take these fake haters seriously…they can’t make up their damn mind…I've been a BF player forever and I can't believe people still hate the specialists. Gameplay wise (skins, models, cheesy quips not included) they're honestly a great addition. There are more different play styles than ever before, and more flexibility when it comes to how you customize your loadout. People always complained about the strict weapon restrictions in past games, and now you can pick whoever you want while equipping whatever weapon you want.
A few tweaks and they can be made even better. Some of the gadgets should be shuffled around to increase the potential teamplay contribution of some of the specialists (for example the repair tool should be made one of the default gadgets for the engineer specialists to better highlight their role in repairing vehicles, like the engineer class in previous games) changes like that would be small but would have a noticeable effect on the overall gameplay. And then obviously the quips need to be removed, or changed so they better fit the overall tone and setting.
If they iron this stuff out then I would be completely fine with specialists being a permanent addition to the series. In fact going back to the traditional class system would feel like a downgrade especially if they retain the same weapon restrictions.
