To be fair you need to purchase a virtual ticket to watch Blizzcon as well ($40 price tag for them).
The only real shitty part about this is the in game reward in a minion. For a lot of people they couldn't give two shits about it. For people who make minion collecting their thing its going to cost them at least $90.
But remember they also sell plushes that come with ingame minions (Hello Carbuncles and Delivery Moogle). Honestly though If I do pay for the minions (And I'm likely to get the JP one for the Lulu minion for the wife) I'll be watching the lore panel (Or trying to) or the concert from the primals.
