Just throwing this out there...

A couple months ago, I re-introduced a friend to video gaming. She had literally not touched a video game in almost twenty years, and the games she played then were mostly 2d platformers and such. It was her first experience with 3d games involving camera controls. She simply could not figure out how to operate the camera at the same time as doing anything else - she could move OR turn the camera, but that was about it. It kind of astounded me, because camera controls are second-nature to me now, and I only ever get flummoxed if the axes are reversed or whatever.

I'd hardly suggest that sub-par players in this game are that way because they haven't played a game in twenty years - but I WOULD suggest that many of the controls and concepts that players consider to be basic and easy are only so because they are a natural extension of other games they have played.

This is mainly a refutation of the suggestion that bad players are bad because they are LAZY. Many of them simply have not developed the skills and habits that make for a successful MMO player. Here's a few things that are common in MMOs that may or may not appear in other games:
- Buffs and debuffs (and associated timers)
- Skills that become more powerful when used sequentially with other skills
- Enmity in general
- Studying online for a fight before participating in the fight
- Studying online for ANYTHING (I dunno about you, but for your standard game looking for hints online is something you do AFTER you've won, or when you're hopelessly stuck - that kind of attitude doesn't fly in an MMO, however!)

It could be argued that there's no excuse for making it to endgame without learning the above - but there is. There totally is. The game is EASY before endgame. You can 1-2-3 your way through any dungeon. Heck, you can 1-1-1 your way through any dungeon. You can gear up in equipment just shy of the best without touching any kind of challenging content. So why would you have all these dozens of skills if you don't need them? Because LOTS of games give you skills that wind up being pointless. Heck THIS game gives you skills that wind up being pointless (sleep, Feint, etc.), even if you DO know what you're doing! It's just a thing that games do. I'd even go so far as to say that for the majority of single-player games, there's one attack or combo of attacks that is ideal, with all the other abilities the player has available being at best, situational, and at worst, completely worthless.

Players coming here from another MMO have less of an excuse, as prior MMOs should give them a pretty good idea what to expect from this one. But players for whom this is their first MMO? The game could do a LOT more to prepare them for what is to come.
