I just canceled my subscription after about 3 months of playing it.
Got up to a level 32 assault rifle blaster, naturally ofcourse... Started getting boring fast after missions took on the usual repetitive course of events and became much less interesting, group or solo battles were pretty much the same all across the board with just the skins changing between enemy.
The final straw was I logged in one day with such bad lag that it took me 5 attempts to make it across Freedom Falls from the hospital to a safe zone after dying, would super jump and about 1/2 way through the jump I'd wind up warping back to the starting point because the server couldn't track the movements the server was so laggy.
I played as "uglygun" on the Triumph server. Might sign back up one of these days but only after a patch or two. I was in a group of people who were some of the first on the server to level up to level 40+, at level 32 the process of leveling up didn't look terribly exciting knowing what it took to get to lvl 32. Also found it pretty boring that all the influence couldn't be spent on things other than costume changes or training enhancements, I was fully slotted with SO enhances and still had like 2 million influence sitting around after creating a 2nd character costume. Most of the level 40s I know have something like 5 million or more influence sitting around not being used.
If I do decide to come back, I hope they don't delete the old characters I had during the time of inactivity.
Though I am kind of interested in City of Villians. That could get me back into the game with some PvP fun.
