No. Don’t change Shocktrain. After I saw how dominant it was, I put all my resources (including some cash) into obtaining and leveling up my four on a Spectre. I didn’t waste all that time and money for you to decide to nerf it so you can make players have to obtain and upgrade something else to stay competitive. (Increasing your revenue.)
I’m sure you’ve noticed players leaving the game or not playing as much due to all the idiotic “economy” changes lately. 2 of the top players in my clan (both were previous leaders) have left due to the greed factor involved. If you want more to leave, including myself, go ahead and nerf the Shocktrain and come up with more greedy ideas.
Leave the Shocktrain alone!
