Just because something has been done a certain way for a “long time” doesn’t mean it is the best possible option now. The amount of active Tremulous players now is a tiny fraction of what it was years ago (Quake 3 also experienced a devastating decline in popularity) .

Of course there were/are aspects of Tremulous that make Tremulous a uniquely awesome game that shouldn’t be abandoned but rather embraced.
