I just cancelled my subscription but I wanted to post my reasons why here in the hopes that someone may actually read it. Here is what I posted in the "Reasons for canceling your subscription:
"Your art, writing and voice acting teams were all superb. A shame that their excellent efforts were tied to a game design that was sub-par at best. Oversize maps, uninteresting gameplay and combat that never flowed or allowed actual strategy all formed a game that was simply not fun to play. Above and beyond all that, however, was the fact that this game did not play well as a multiplayer game. For years my group of friends have gotten together every Monday to play together. We know how to work as a team, how to control the field of battle and cover for each other. But playing as a four man group we found ourselves bombarded with what we came to call "magic adds". Elite enemies dropping out of nowhere with no chance to crowd control or even arrange our positions. We were wiping on content six levels below us due to two elites and three silvers dropping into fights out of nowhere. Out in the general world we found ourselves taking the same amount of time to do quests six levels below us as we did to finish quests at level. At no point did we feel like our efforts and leveling were actually making us any more powerful, simply raising our hit-points so that our deaths could be slower and more painful. Thus I, my family and my group of friends are all leaving your game. You have a good team of artists, writers and actors but please spend some time and money on some decent game designers."
TL;DR explanation is that I think that the art of this game was well done but the actual game part was horrible.
