Is it worth using gems to upgrade my training fields to level 3? I don't buy gems, so they are hard to come by, and I usually use my gems to beat the boss the last few times to get the + armor.

I don't use monsters nests (except for the 1 sqr) because I don't play the game every 4 hours.

Sorry if there is already a topic on this, but I couldn't see one.
