Just to make it clear, I am leaving the game personally, not Luciform. They are staying under a new leader, NTK.
My main issue is I have a very high playtime. I like to play A LOT. Thus, I want A LOT of content on differing areas that I can engage in. 4 "normal" dungeons and less than that in their "hardmode" equivalent along with OWPvP that has NO objective, reward, or incentive to get people to go out (besides fun, which does not seem to be doing a great job at this time) does not provide me with a lot to do. In short, many of you are correct, I burned out on what there was to do. That is because compared to a majority of other games, past, present and future, there is LITTLE to do. Maybe I am just spoiled with other titles, but it boiled down to me not enjoying my in-game time.
Keep in mind this is all my personal opinion and experience, others are loving the game and I have no issue with that. What it all comes down to is that I was not having fun with the game in any major sense, and thus decided to quit it. While I like to invest lots of time and play at a "hardcore" level, at the root I want to have fun.
I would like to thank all of you that added to my TERA experience in any way. I may pick up the game (at a more casual pace, as even if they did add a ton more content, I would still be cautious for my own sake) or you may see me in other games in the future. I usually play under this name or some variation of "Mizu". I will most likely still lurk around these forums and others for the fun of it and to see how things are going, though on a much less frequent basis.
Thanks and good luck,
