The art of learning to play well comes from both sides of the table.

People must be willing to teach as well as be willing to learn but unfortunately there are bad eggs on both of those sides that makes such a thing a lot harder.

But honestly i blame partly this problem on SE, everything in this game other then optional content such as extreme primals or raiding is face roll easy and offers no reason, no need and no motivation to ever become better since the few things you must do that actually requires coordination you can just hide alongside the other 7 players that will beat it for you.

What this game should have had from the beginning was a main story (and its dungeons) that became harder over time with more complex bosses so people would have had little choice but to become better and better.

But then again this is a casual game....
