I have played this game on and off since the beta of City of Heroes an age ago. I gave up on it initially because I grew tired of the same old missions over and over again.
The last time I came back when I joined groups to do missions I was too busy buffing everyone and controlling my pets or healing or locking targets down that I could not really spend any time reading the conversations or the smart comments the villians or characters say. I used to rue that often.The only time I truly appreciated a story arc was when I soloed them.
Let's face it when you pug and run around doing other people's missions you are not actually paying attention. So when you really want to savour this game the best option is to do it alone or with like minded folk.
I do not think AE has changed that. It instead has opened a whole plethora of player made missions and ideas which when I finally find some way of actually finding a way to weed through the pharm ones I will be able to enjoy.
Perhaps it is showing a not great side of CoX but then when I used to wait about in Nerva waiting for some one to come help me with my mission it was not much fun either. At least of late in Freedom and Virtue the population seems to have grown.
