it is.. if there are stupid people playing it...
like a while ago, some people were not following etiquette.. you
are whacking away at something, they use their ranged attacks to
"steal your kill" or worse, you're held up by monsters and they go
steal your monster drops...
that's irritating...
however, if you have a lot of people who are nice, and there is
some interaction through talking and some trade, it can be nice

as like life, it's what you make of it...
someone can give you a pile of lemons but you can always make it
seem terrible, or it could be a good thing 
just like there are people out there who keep complaining but miss
the wonderful blessings they have.. it's almost tragic..
