Possibility of cosmetic options for microtransactions.
cosmetic options. I really can't think of any other cosmetic options they could put for sale besides new heroes that do the same as old heroes, but with different art and voiceovers.
what else could it be? new boards? "platinum cards"? green fire mana?
if we really get more heroes through microtransactions, I'll definitely buy them. maybe not all of them (I probably won't be buying any orcs), but I'll pay any price to replace gul'dan and rexxar for cool characters like sylvanas and... I don't know, maybe kanrethad or archimonde.
actually I'd pay 100 bucks for archimonde
