Please help/critique this home game structure

Im having issues with the poker league I am in. 10 of my friends and I started this poker league. Due to everyone being very busy we can only play 1 day per month. We play 2 $15 games every month on the same day. There is also a $15 league fee every month that pays out the top 6 at the end of the year. Points are awarded after every game to determine who the top 6 are:
1st- 16 pts 5th- 8 pts 9th- 3 pts
2nd-14 pts 6th- 6 pts 10th- 3 pts
3rd-12 pts 7th- 5 pts
4th- 10 pts 8th- 4 pts


Thats all fine and dandy. My issue is the blind structure. Blinds are 12 minutes. Here is the structure:
Starting stack is $2500
12 minute blinds
50-100
100-200
200-400
*250-500
300-600
400-800
500-1000
750-1500
1000-2000

*"We got rid of the 25-50 blind and added 250-500. This will speed up the action early on."

This is a very hard game to win. The blinds increase so fast that the games seem like a complete crap shoot. How would you guys play this type of game? Anyone have any recommendations?
