Reasoning for removal of TP, but not MP?

[Shurrikhan]

part of the reason for removing it was likely to reduce dev complexity, which is also probably one of the driving factors for the simplification of tank stances. every time they add a new job/race it multiplicatively increases the maintenance requirements, and they are quite likely realizing that they have to do this to have expansions in the future.

Then, honestly... they should stop adding races and jobs if they can't even maintain a standard equitable to their first expansion.

Of course, games made in the early 2000's had no such issue, but /shrug.
