I've thought of that too but it would probably change the meta and it would be super OP. It means on any turn you want you potentially do the following:
2mana - 1/1
4mana - BoK it to a 5/5
1mana - Blessing of Might it to an 8/5
1mana - Blessing of Wisdom
1mana - Divine Shield to kill an enemy minion
1mana - to divine shield it again
10 mana total
I mean sure it's a nuts combo and very unlikely but can you imagine the outcry the ONE time someone pulled it off? Even just a 5/5 with charge for 6 mana is pretty severe. Most chargers in the game die if used for removal and those that don't (argent commander) are considered OP.
The odds of that happening are so astronomical that frankly it deserves to be a charge to allow you to benefit from playing so many cards in one go. imagine doing all that without a charge and then u get shadow word: deathed before you can attack with it or god forbid mind controlled. thats 1 card to kill 6 and on top of that u got nothing out of it. or worse still u are forced to sit there holding onto that amazing combo and not being able to keep any minions on the board long enough to use it, becaue if your planning to us it on you hero token its because you litrerally have NOTHING ELSE to use it on, immagine doing that combo on a taunt monster like the goldshire soldier.
This is so wrong. No hero power that effects the board can be considered close to as bad as warrior's or hunter's.
while i agree with you the hunter ability lacks utility and the warrior one may seem useless both of these effects still benefit you the turn you play them, i've lost to that hunter chip damage so many times.
And for the warrior that armor keeps on stacking, i've seen it get stacked as high as 14, the armor also combos well with the instant attack capability of you champion with a weapon.
The point they are both INSTANTLY effective and can be used to with the game that turn or for the warrior effectively boost there max health pool above 30 and make it take that much longer to kill them. In this game where you field can be wiped in a single turn if you don't have to deal instant damage to help even the play field you are left in the hopeless situation summoning everything you can, having it killed while your opponent can summon more monsters to keep attacking you with.
and as for "changine the meta".....THIS IS THE BETA! We are here to mold the meta to where all the classes are viable and balance the classes as best as we can before the game goes live. none of this is set in stone and now is the time to make changes.
