Everything, as far as I could tell.
What does not
What was not tested
Had some FPS issues, most likely stemming from my old laptops hardware. Closing the launcher window after the splash screen loaded provided some improvement. Did not use any modifications. Loaded fresh install of wine, coppied the installer from another folder, and let it do its thing. No errors, no problems.

Couple of items to note:
1. Need 32bit PREFIX, I could not get 64bit PREFIX working even if patches. I used a 32bit virtual machine to build. You could also build in a chroot. Seewiki.winehq.org/WineOn64bit for more information. # TODO: need to confirm
2. The default Windows XP profile does not seem to work (at least with wine-staging-1.8.9), after I changed to Win 7 profile, the launcher started to work.
Winetricks installed in my PREFIX:
As of 24.01.2015, it seems that wine-staging build is required in order to launch TERA-launcher.exe properly. It can be found at https://github.com/wine-compholio/wine-staging
It will still not work though, you need to remove boost_interprocess stuff (which then will get recreated, so this is required for every launch), by executing rm ~/.wine/drive_c/users/Public/Application\ Data/boost_interprocess/* or whatever is correct for your env.
Performance seems to stutter quite a bit due the Flash based HUD, which can be tested by hiding the HUD using ctrl+z (default keybinding).
There is another performance related problem, where most actions lags quite a bit behind due the UI being fairly slow. Hiding the clock and FPS counter makes the UI more responsive, so disabling these two settings is suggested.
Installing new Flash with winetricks
sh winetricks flash
seems to help by few FPS points.
Removing mini map (N key by default) also seems to help by few FPS.
