I can't login to write a comment for some reason so I will reply here:
The MLG times are misleading, all the weapons are on a drop spawn and don't spawn until technically 4 seconds after they are supposed to so the times are as follows on 15mins games: Rockets: 11.56, 8.52, 5.48, 2.44. Snipers: 12.26, 9.52, 7.18, 4.44 and 2.10. So rockets are 184 seconds and snipers are 154 seconds. Hopes this clears it up for you.

Thatnks. That is really useful. I will update the times and post an update.
It will be in 1.20. (1.10 has already been submitted for approval).
