Besides those baised arguments there are other hard data that can tell us what times were the best for TERA, that hard data point out inmediatly to TERA around 2014-2015 but as always people here will try to tell others that their thoughts are the truth, not even "real data" they can share or other people can investigate.
Get real, if you guys think that your own idea of a classic server 2012 is the best, that again failed world wide on launch and had to make a lot of changes in the first year the game was released, then there is no hope for you at all.
First Tera was released in Korea and it was insanely successful launch. At release date they needed to add more servers and in insane amounts. But hype was short, around one month.
PRoblem was they released 48 lvl content only. There was not endgame. Just beach with big crabs.
People had wait realy long time to get 50 lvl endgame content. Ofcours, they was complain. So problem was not the game just the manegment.
After thet KR finally reased 58 lvl path - Keilaik and this was most succesfull patch of the game at P2P era.
But they did not released this for EU and NA. They waited for next patch. In the end they for over year holded release the game for EU and NA what ofcourse cause financial problems for Frogster.
Finally version released for EU and NA was not Kelaik patch. But patch witch new region, mobs that give very much experience, gold and easy to get items better than the ones that drop from Kelaik patch instances what make endgame no existant. Because there was not Nexus and Shandra Manaya. There was not even battlegrounds. They did it again - released game without endgame content. Again, problem was not game but management.
Beside you say F2P era was more successful. That is obvious F2P games are more populated and generate more income. This model actually destroing MMORPG marcet because it make worst trash game succesfull. Look at something like Genshin Impact - are you call it good game? It's an trash. But it's F2P.
Same here. Success with come with F2P system does not related to quality of game but just payment model and fact it became free.
Did you ever play anything post gunner/brawler/ninja/valkyrie? Did you play nowadays all the content Tera had to offer? Did you ever play for at least 3 months consistently post 2017?
There is no PvP server so there is no way for me to even touch it.
