What does "drop" mean? Remove it from the servers? And as far as I know pt4 still exists. Do you play lots of tournaments? If that is the case you should try and get the league you are playing in to include pt4.
If however, you only play for fun.... why don't you just play pt4?
What I would like is for t2 is be unn00bified and for there to be new maps. Yay!
