I think everyone needs to give this a chance. There are already rumors of a brb coming out later in summer, which would mean another layer of depth.
Sure there are complaints. Balance seems to be the biggest. That I believe I have a solution too. Everyone agree on a Warscroll size. If one army ends up outnumbering another, then the Sudden Death rules apply.
My only question: On some of the warscrolls, in certain entries like Undead, Daemons, and Lizardmen they say that wizards from their faction know a summon spell. It then gives a casting cost and says you can add a unit of the summoned creatures to your army. One in particular was Saurus Oldblood. Can a Slaan really summon a Oldblood each turn if the cast is successful?
Monsters are viable again. Cav are viable again. Undead can mix. Chaos can mix. Cannons are toned down. Magic has been toned down. Beastmen and Brets have updates. There are no more required selections, no more core tax. Most importantly there are no more $400-$600 buy ins. A single battalion box is a good sized force.
Additionally, we as a community could adapt 8th ed rules for more indepth and classic games if worse came to worse.
I for one will be playing this as soon as I print the PDFs.
