Only thing that annoys me most, is NOE bomber missions. A set of 4-5 lanc groups go over a field and take down all hangers, and town before anyone has time to react and the base is already lost. Spies however my impression is if someone is going to spend an extra 15 dollars on a video game simply to shoot down a few goons is seriously in need of a new hobby. Saying that if someone wants to spend 30 dollars on a video game a month so be it! Hey I spent 200 on my flight setup, why can't the next guy spend little extra achieving his ultimate goal of shooting down the most goons a month?
Instead of paying 15 for a spy, simply watch your dar circles, when one starts flashing with no Dar around it, pretty good idea either a GV or NOE raid is Inbound. Much cheaper and taking an La7 up to intercept you can easily get 5k in a minute or two so your well and ready for defense.
just my 2 pennies.
