Crate Tycoon Achievement

Okay, so I've been wondering about that new achievement system they put into the new update of Crossfire. And one of the achievements, called "Crate Tycoon" has the effect of increasing your win rate. But what I want to know, is how much it increases it by, and if it's a drastic change or not. And also, I want to know that if you buy 5 crates, does it count for the 2nd stage too? like is it like if you buy in packages then you get the achievement or does it stack up over time? Like if you buy like a 30 crate package, will you get both stage 1 and stage 2 completed? and then if you buy 20 more, will you get stage 3 completed? Sorry if this is confusing.

I think you need to buy then separately say you need 5 for the first one and you buy 10 the extra 5 wouldn't count for the other one.

I said I think :P

The achievement system is very much like the badge system, once a stage has been completed, the score does not get carried on to the next stage.

I decided to test this little achievement out. So I bought 5 DE Camo crates (which gives me the first achievement). Well, I guess it increases the chance very slightly because I only saw it once. And that was the first time in history that I've spun DE Camo crates and saw a DE Camo... Still... a little ticked I didn't capture my first Camo
