There are genuine reasons to be disapointed with Age of Sigmar, it doesn't offer the experience some hobbyists will want, however, this is the game GW want to make and they want to appeal to the type of customer that enjoys that type of game.
There are options for you if you're one of these hobbyists who is no longer able to enjoy the game GW makes. Raging about it achieves nothing. Going on and on and on about how GW is a crap company achieves nothing.
The odd thing is people feel entitled to rage and shout and scream about these things, they have a really odd view of how the customer/supplier dynamic works.
A company has to supply a product that works as promised, when you buy a rulebook and some models from GW, that's what they've done. Supplied you with a rulebook and some models, if the models were faulty or miscast, you'd be entitled to a replacement or a refund. If the rules were misprinted or missing pages, again, refund or replacement. (incidentally, part of one of my Realmgates, which are made in China, was missing from the bag, GW sent out a full box to replace them without delay, this is the second refund or replacement I've had to get off GW in the last 4 years and both were on terrain kits made in China)
You're not entitled for that game to stay on the shelves forever and ever, you don't get to decide how long Games Workshop have to wait before they change things.
If you don't like a new game or a new model or how they release new rules, you don't have to buy it. That is all you are entitled to, you have the right to withdraw your custom.
You have the right to go to another company, Mantic's Kings of War is a mass unit based fantasy wargame, designed in part by one of the team that made stuff from Fantasy. Avatar's of War make Warthrone, there at 8 editions of Warhammer Fantasy that all still work fine.
