I think that the concept of Wondermats is a really bad one will make things even worse - because of the imbalance between factions.
The lack of cats can be compensated by playing more... but the imbalance will only grow if outposts start producing materials that give advantage in battle. Things are bad enough as they are, with the existent OP mats.
But wait! I have a solution which may satisfy everybody.
I think it would help to give to each toon a small amount of cats (like 5 stacks / week), no-trade.
What will this do? It will help advance people who have very little time to play, which is what was intended. At the same time, they will have little influence on those who play a lot.
As an extra advantage for everybody... it would be nice to come back from vacation and find 15-20 stacks waiting to be used.
