I think that's patronising and oversimplified, and basically wrong.I think anything you personally don't like flying against is a crutch to most people.
Oh I hate imperial aces, boostwing is a crutch.
Oh I hate turrets, turretwing is a crutch.
Oh I hate extremely accurate alpha strikes, jumpmasterwing is a crutch.
Turns out someone will dislike most any singular element of the game so you'll find most things called a crutch depending on where you look and how hard you listen.
People don't like these things for a reason - because they feel they remove skill from the game. You can't simply apply that label to anything you don't like; you can easily apply that label to things that let you shoot perfectly well regardless of your positioning or that let you correct your positioning after seeing everybody else's.
But that is simply your opinion of what removes skill from the game, thus reinforcing my point. Some people think ps9 ships that boost remove skill from the game. Some people think torpedos giving 4 hits in a mega alpha strike removes skill from the game.
There's no universal definition of "skill" in xwing and as such any opinion can be formed about what adds or removes it to the game, coming back to the point of basically anything can and will be called a crutch when people don't like it because they think it removes 'skill'.
Sure, it's all opinion, but I think it's difficult to argue that not needing to predict your opponent's move isn't removing skill (you might still benefit from doing so, but it's a lot less crucial). Does it replace it with another skill requirement?
