Collection - part of the game?
Collection is part of the game, gathering as many champs as you can, somewhat Pokemon style. I have heard this view expressed quite a few times.
My question is, what will happen when wish Crystal's come?
I personally have little desire to collect all of the champs. I like to play the game at leisure and ideally with champs that are fun to play and help me complete the content.
I am assuming that wish crystals, if they were to become common or highly accessible, could significantly reduce the acquisition of the less desirable, higher rarity champs.
