First of all, Tanki focus on your current plans. (machine gun/minigun) Stop getting sidetracked! Secondly, why must you give this out right after the huge sales we just had? Think about it, this is only good for buyers and is most likely a ploy to get them to buy or do you, the people in charge of implementing these updates, do not have some common sense? (No insult intended.) Thirdly, I'd rather have permanent things rather than something just for rent. Fourth and finally, the prices are outrageous for just renting for the time period of less than 2 weeks. I'd probably rent some of this caliber if the prices were cheaper. Might as well buy an m3 or something permanent for that price!
On the other hand, good idea TO team! The idea of customized tanks spices things up a bit, especially for people who are getting bored of this game. Maybe you can also look into the idea of adding Frost or new paints you can add from time to time as paints like Moon Walker or Traceur that we get to keep permanently, but only get to buy it for a certain/select time period. A cool/good looking paint that is not feasible to buy anymore after a certain/select time period will also be envied by newcomers. I'd certainly love having something people cannot get; it sets off a sense of pride. Also, most people will probably not buy these, but it does not mean they are not a good idea; they are just implemented at the wrong time. (Again we, the people of tanki, just had a lot of sales. Most of us have our crystal supplies really low or at least not enough to buy any of these unless we buy crystals ourselves. Try giving us a heads up that this is coming before sales, at the very least.)
