Regarding the Power calculation changes:
With 2.3, the power calculation is changing:
Power is artificially increased for players that do not use all 8 units during matchmaking to discourage the abuse of the matchmaking systems. If you have less than 8 units and you are above rank 20, purchase additional units and take the full 8 units team to the battle to get rid of this penalty.
Your overall power has lowered, because we no longer use all 8 units to calculate the figure, but only 4.
Hope this explains it!

Yes. Pls solve the issue. I spend so much $$$ and only win/lose ratio 2.5. Those recruit 4 units, some time I can see their ratio is 25:1 to 120:1, no ppl come here to play as loser.
