Ok MW people...enough of the complaining about the rewards.
Let us give GREE some ideas about rewards and units.
GREE will listen because our ideas are completely free... And they maybe even get paid for when the longing for these rewards are high enough...
I will make a start:
How about a new bonus unit!
The XP Muncher Tank. 2187 / 1765
-20% XP from battles
Reward from a boss
well, how about that?
