Tera doesn't really get a lot of new players that will actually stay in the game for longer, most of the active player base comes from the veteran players.
The servers are pretty unstable at the moment, at least on EU, if you don't have a crash at least twice a week it's a miracle & the maintenances/ patches are Always delayed. The only worthwhile server right now is Killian, even thou they combined some of the other PvP servers into a server called 'Icaruna' but that is filled with people who have no clue what they're doing.
Endgame of tera still pretty much consists of nerding the same instances over- and over again.
MCHM is still the hardest one by far.
Many of the current players joined tera After the Wonderholme patch, so basically PvE raids are mostly based around players who've never ran MC and they think that WH is hard. Finding Experienced players for your raid isn't really that easy, since most of the veteran players have either quit/ transferred to NA or gotten bored of doing instances.
There's going to be a new T15 patch "soon"(no idea when it's coming out, supposedly they said in the end of summer for EU but that's gonna get delayed.) which includes new instances and supposedly a new "Hard" instance that can be compared to MC. But from what I've seen in K-Tera it isn't really that hard, the first full clear was only a few hours post-patch.
If you got bored of the game once, there's really no point in trying it out again, unless you have buddies to play with.
Playing anything with friends is always fun.
Been playing Tera on EU since CBT & still playing. I have no idea why.
If anybody's playing on Killian feel free to poke me in-game 'Chirin'.. :p
