Deathdealer, the colored evo shards are not impossible to farm, but you need 375 per toon. So you will need to extensively farm other dungeons or LoL. Its all a choice on where you want to farm. You will also need extra shards to evolve all other new toons you may want.

Buying all the awakenable materials will become very costly using awakenable frags with all the availavle awakenable toons and future releases.
