LOVED IT! It gave you that moment of invulnerability, and the power to heal your team mates by running up to the damaged ones when you reached 100!

It says they'll have double crystals in battles, but I'm not seeing any. Also, 1200 kills a day? Anyone without a premium account or all the players who don't buy their crystals, would have to spend the whole day to be even lucky to get 500. I think it would have been better to just give discounts in the garage and a holiday paint.
