I have both of the mage tower forms for Guardian and Feral. Guardian was only a cakewalk if you had the right legendaries and a considerable amount of experience soloing stuff, while Feral was a cakewalk if you had a functional brain. I’d actually argue that if getting the form was as easy as the OP claims, then that’s all the more reason for Blizzard to turn down the request; that you had roughly a year or so to do this one “easy” thing to get the form and you blew it.
I’m more curious as to why try so hard demanding something so unimaginative? Why not covenant forms? Why not something we’ve never seen before? Why does it have to specifically be the mage tower forms over all else?
