I would welcome more ways to add saved weapon sets.

5 is the current maximum.

Win some in plots/battles, add by millionaire center or Cash shop. Even if you want to add one at a time to test it out.

I like this idea simply because I want to have a set for all Tiers because I have multiple battle pets and it sucks having to adjust certain sets to accommodate the pet I want to battle with. More sets would be a god send. Plus your idea of introducing them is great ways as well.

For the Mil Center I think they should start out at 5Milion and increase by a factor of 2.5x and for a Cash Shop probably 25CSC per set. Thoughts on this?

Yes increasing similar to how they do for additional pets would be good.

Yes, it's a pain in the butt and I only have two battle pets.
