Thinking about the previous post reminded me of this old saying:
If all you've got is a hammer, everything starts to look like a nail.
Which is true. But also true, and more applicable to WoW, I think, is this:
If you've got a whole box full of different tools with little wiggly bits on the end and you're not quite sure what you're meant to do with the ratchet except maybe "pretend it's a noisemaker for a party," and if almost everything you've encountered has been nails, and maybe the occasional screw and hammering that in like a nail worked ok in the end, it's easy to forget that you're carrying around that whole box of tools and instead just always reach for good ol' hammer.
God I'm good.
