The only problem with those skills comes with the fact that in the previous game, you played as source hunters and they did those abilities without Source, which just...bugs me.
In a sense you can say its bc those characters were just that strong bc they were the "Defenders" and what not, but there was no other mention of those abilities being a source thing. And in OS2 we're supposed to be the chosen and powerful again, so I mean, idk. It's just me tho.
