Permanent ZP weapons...

I suggest that we have the ability to by permanent ZP weapons from the item mall, for about 2.5x the 90 day price. EX: M4A1-Adv costs 2800 for a week, 5600 for a month, and 14000 for 3 months. How about letting us buy it permanent for 35000 ZP? A lot of people probably would like a ZP gun like the M4-Adv, but don't want to have to keep renewing it indefinitely, so they don't buy ZP. Also, if you like the game but don't play very often, why bother getting a temporary gun that you'll use only a few times before it expires? Give them the option to pay a lump sum and get it permanent would sound a lot more appealing, and would possibly persuade them to pay the extra money. I for one love the dual Colts, but I won't pay 10 dollars of the little money I get to rent a secondary weapon for only a couple of months. Saving up for a bit to buy them for keepsies on the other hand, now that I would definitely consider doing. Overall, the amount of money that Z8 would gain by both casual and hardcore gamers buying permanent weapons would definitely outweigh the amount lost by just the tri-monthly purchases of serious gamers.

Besides, most long-time supporters of the game already have permanent upgraded weapons (from bonus points), and either already have or very soon will have stopped buying temporary guns. Thoughts?
