The way i see it,it's the price you have to pay for joining (Or even hosting) a hobbit
map.

lairosen the prem timer is fine, blitz player should stop playing at hobbit map, and
hobbit map is actually the default map of dd select room, i suggest bringing old default
map back... the most funny complain players would say: BIG MAP HOST NOOB lol

16 players on NWO1 and half my games still go 15mins. Hobbit map has made
everyone rushing tards with torps and armor. Change the map, change the
set up, and you might get better players and premium every game. Don't get
me wrong, I'm not blaming or accusing you. Ever since Blitz default map was
changed to hobbit, it's become a breeding ground for terrible players. Use any
sort of range and you get flamed. Good job to whoever thought this was a
good idea.

The solution is change the map. A lot of people are tired from playing hobbit map yet no
one bothers to change it when they create a room. The solution is not adjusting
premium, its using the variety of maps you have available.

Well evidently its still too long because 80% of my games finish before premium starts

Premium actually kicks in at 4:30 or a bit earlier so you might want to change
your story.
