Turn Based - is a soul and spirit of Falluot and that is what all real Fallout fans LOVE!
Real Time is fun, but it was made to attract the modern compost of gamers and speed up their fights.
Fallout is like chess, fights are based on strategy. The only bad thing with online FO in turn based, is that a lot of scums are draging time in fights just to mess with players. You are already planning to cut TB balls off. How smart is it, the time will show.
Eliminating TB fights is not an option. Better think how to optimise TB fights time, and minimize waiting factor. After you do that right, the question will be if Real Time fights are needed in FOnline at all!
