Balance is never perfect at launch and if you dont like snow maps just quit when they come up.
With all the "community requested" features coming up it is likely to see a map selection pool before playing.
Oh and asking for refunds is so dumb. Only a couple of times steam has accepted refunds and that was for completely broken games like WarZ.
Most of the issues youre talking about are balance and maps, both of which who will get fixed over time.
You want a refund because you find the meta game broken? thats laughable
