I've only made 2 forum posts, I'll be getting Lordly Legionary in a few days so that's where I'm at as far as number of days in game..
I've got Tower also. He's one of my 3 (including Ninja). The third one is Norog. Both were pulled from blue shards.. So to you noobs out there don't get your hopes up on those leggo shards.. I'm 0 for so far!!!
Also, I would advise any new players out there to not focus on getting new champs that's not the answer. Get books for the ones you already have! Rest assured they'll dangle those shards in front of you 24/7.. Like the state farm commecial and the dollar bill on the fishing rod!
