So The Witcher plays like Dragon Age, which plays like Final Fantasy VII, by your logic.
Also, you considering the TP system to be anything like the stamina system shows that you don't know what the hell you're talking about. Stamina was terrible because it was used for every single goddamn thing. TP is only used for weapon skills. in 1.xx, you had to consume stamina AND TP.
A red mage with Refresh for MP regen on mages and Haste for TP regen on melees should be very nice to see.
I think we still start off at 0% tp, it just doesn't degenerate as it currently does so we can use it for later.
