Mu ing any turret or hull is mostly double the price of next modificaion, i mean full Mu ing it. It will be nice if you Buy next modification but you can Mu it till 10 which will cost very less and still valuable, its different if you are too less ranked and lots of crys, only mu it fully if you have that much crys that much you need to MU it, this will help - http://en.tankiwiki.com/Micro-upgrades, here you can find cost of each step of mu for all turrets, hulls and modules.

oh nice

I like firebird because i like seeing those hulls go red more redder and most redder, so hot till then they die. Only turret which can kill even after being dead. it looks are also good in m2 and m3. Only i dont like m0 because it doesnt do red too much, sometimes we cant even notice it. Firebird means doing red red red! i like red color! :D :P

NICE MAN

I think its a good update but it has made paint just a mess. People are made to buy paint for only beauty which serves no good thing in it, except those paint which are for camouflage but they are made too cheap which will make people think its useless but the mods are very useful, all the mods at m3 if mu fully serve best protection that is 50% so i liked the mods too much. ^_^
