So they sat on the table at HS office meeting room and they have the following discussion.
Master Balancer: Ok guys Shaman sucks, let's fix it
Bob The Troll: Oh i have an idea sir, let's give them a 7/7
Master Balancer: Excellent idea Bob, let's do that
Bob The Troll: oh oh oh sir also let's make have a non-sensical low overload let's say 2 crystals
Master Balancer: Sure bob sounds balanced enough
Bob The Troll: Oh sir and a final addition that i think it's very much needed, let's make it cost 4 mana, on top of that let's introduce another low cost minion that can unlock the overload crystals next turn.
Master Balancer: That's sound great bob, you are a genius, a 4-mana, 7/7 with an insignificant overload what can go wrong, in fact it's a bit weak let's also make it common
Room: "Eerie silence"
Master Balancer: Release it!
Bob The Troll: Ok these guys are bigger trolls than me i quit.
