I can again only stress that most of this discussion is about opinion and preferrence. Some prefer TB some RT.

It would indeed be much more helpful for the games progress to look for ways to improve the existing system.

That said:

I also agree that the actual combat sometimes seems pretty slow, especially when doing fights all over again for the x-th time. The AI is taking sweet time to decide what to do.

For one i would go for simultaneous movement of same turn characters. That could reduce waiting times a lot, especially in larger encounters.

(since i did not manage to read all 80 pages, sorry if this was mentioned already)
