If a game isn't fun, then you simply shouldn't play it. If you logic is as follow :
"Well in 5 more hours I'll hit 50 and then there will be something new"
"If I grin through this one dungeon 60 times total, then I'll be able to do interesting content"
"I have to farm a gathering profession to compete with teleporting bots t pay my bills, but I won't need it as much wnen I get enough money.
And the FINAL sin in any MMO is.
"Wait till next patch it will get better". Why would I want to wait for 3-4 months to make the game more interesting, especially when you note that many times patches are failures, broken content, no proper class rebalances, etc. Thing that should be hotfixed the day they are noticed, should not be held for almost hald a year of you waiting for shit.
Game needs to be fun, always. There is no excuse to shove artificial bad content to to simply draw things out for the same of a timesink.
