Not necessarily good or bad, more so a midfielder playing wide on one side and a more direct forward type on the other side is very Wenger-esque. (Examples Alexis left/Ramsey right or Cazorla left/Walcott right). But like you said Wenger didn't have a Partey type in midfield which would have aided a lot and in general we all saw the flaws in all of Wengers sides. Balance is of course the most important thing now. We used to suffer committing too many forward, now we seem to be constantly playing with a bit of caution to our game. We need balance.
