Fully agree with Sasen and Shiruu, They're massively overlooked and are definitely among the strongest Scoia'tael gold right now. Iorveth in the other hand. I love the card, I truly do and in theory, he should be awesome since he's back to what he used to be in the closed BETA when he was a must have card but truth is, the fact that pretty much everything can damage gold units now change a lot of things and he kinda feels like a "worst Eskel" in comparison.
Don't get me wrong, he's still good but he's not the massive demolisher he used to be in the past.
Also I assume Vill is Borkh and if so, I really don't like him anymore since, just like any gold card that have a delayed effect, he can just be killed or worst locked (I say worst because it's far easier to do and requires just one card in any deck really) he's just a 8 str unit with no ability that takes a gold slot. And not only that but you also have to keep an eye on the board, making sure you're not controlling the strongest unit on the board. At this point he could destroy the strongest enemy unit he wouldn't even be OP.
I do respect you playing him though, I believe it's great that some players keep playing those "high risk high reward" cards and I also do it myself (I have decks with Priscilla, Yen con and Triss butt) but not with Borkh, he just didn't give me satisfaction in my last try.
