Gotta say, I'm with Bijou on this one, didn't get any hostility out of my reading of it.
My take was totally one of "this game is so complex, and SOE does such a piss-poor job of providing documentation, that veteran players often don't really know how stuff works".
I've been playing since 2000, and I'm still running across stuff I didn't know, that is useful. I just learned last week that you can configure a key for "cycle through nearby corpses" and "cycle through extended targets". Probably mentioned in a patch note when they were introduced, but was probably on a break when it happened. That one tip alone (corpses) will save a ton of time when looting lots of brownie-size mobs. They're always a pain to target while looting.
They have those tips which show up when you log in to the game. Unfortunately, they have VERY few different ones (maybe 10). Having said that, one of them was a huge tip for me. I never knew you could dump one bag's contents to another bag by control-clicking. I'd love to see that tip screen greatly expanded, and have them put a couple hundred similar tips in place.
