No. For example, if you have done microupgrades for M0, lets say 5 steps, and will buy M1 - then it will be resetted to step 0. But do not worry, M1 is anyway better than fully microupgraded M0. You can see a full list of microupgrades here: http://en.tankiwiki.com/Micro-upgrades For example, for Railgun: http://en.tankiwiki.com/Micro-upgrades_Railgun You are paying for the better weapon, you are strenghten that others in the same battles. The only 'price exception' - if you will do microupgrades fully, you will get a minor discount. But it is still much more expensive to do such full microupgrade than just buy M1/M2/M3.

Of course no, as it had been show here multiple times - totally different steps. 1) Instead of 200000 crystals you will buy 100000 crystals for 75% of price. As you might see - it is about 62.5% discount. 2) But at the same time, if you are consider it so - what will I get for 75 euro? 2a) Previously, 75 euro = 150k crystalls + 200k bonus = 350k altogether. With DCC - 350k * 2 = 700k crystalls 2b) With the current discount you will get about 803k crystalls. Can be considered as 56% discount.

Last year there was just a 25%. :(

They are the 2nd. Winner is: https://www.youtube.com/watch?v=lp5bxZdev2g

50% discount for Railgun had been twice at February. Nice sale, of course just 2 weeks after 50% discount, but at that time I did not receive X2 :) Hopefully this week I will get it, much more tries. Unlucky I do not need anything for the next 4 ranks :( So I will buy a lot of supplies! :D
