SCC, you cannot argue, logically, that somebody's proposed system is too complicated when the current system is more complicated. You also cannot argue simultaneously that you "get" bonus OP for specialist builds, and DTC is the baseline.
Though it is interesting, I can't say I particularily care about the differing versions of people's recollections over the history of DTC/ITU, as related to game mechanics.
Also, that DTU doesn't have to be found, DTC is for when you haven't found ITU yet, ITU is not found by default, all do not matter to my opinion that there is no need for both to exist. Stop typing it. We all know that. It is irrelevant. It doesn't need to be said. It just obscurates.
