Discussion about TB vs RT is an very old discussion. Current game interface is suited mostly for TB, and by interface i mean not just a fancy pictures, but also amount of useless mouse clicks you have to do to perform basic action - switching cursor modes can be a pain in the ass sometimes during RT (That's also why we have hotkeys for some of the things - like aim modes).
TB doesn't scale in highly populated areas/encounters (imagine 60 players in one encounter doing PvP... you do your move and then you go drink some coffee, take a dump, take a shower, get back, wait a little and then it's your turn again if you are still alive
.
The game should have only 1 mode - RT, but not the RT that we currently have (using current RT is like riding a bike that has a dildo instead of seat, some people got used to that, but it doesn't change the fact that shit is still ugly), not even the one that we have in FT:BoS (we need close to that one, but better, some sort of hybrid between FT:Bos and RTS game like interface - that worked pretty well in such games as Rage of Mages/Allods and Evil Islands series). Unfortunately it's impossible to fix without rewriting parts of FOnline engine, so it's not going to be addressed anytime soon or ever.
