From warseer:
"No points are confirmed*. But there are certain slots which have to be filled, and certain bonuses and penalties for outnumbering and being outnumbered and the tactical options would vary depending on unit choice. The fear, you could just field Nagash and Archaon versus 2 bretonnian Questing Knights are completely absurd. In addition there should be scenarios released. GW provides the game basics and the miniatures; the players can tailor their "individual gaming experience" from this. In addition terrain and positioning will play a big role, he spoke about special rules through terrain. The past core units, special units and so on will act between each other mostly on the same level. Incredible models like Nagash are more part of special Scenarios or huge battles. If you want to line up a box of High Elf Spearmen against a box of Imperial State Troops, you won't have big difficulties. Additionally fielding 8 Silverhelms on one and 8 Knights on the other side - also not a problem. Special units are also on the same level and have additional rules. Phoenix Guard vs Greatswords? Balanced! Human wizard vs. elven wizard? Balanced.
If the Elf player now decides to add a box of Black Orcs and the Empire player takes another box of State Troops, the Black Orcs are stronger, but the Empire player gets an advantage for synergy. It also depends how you position, buff and equip your Troops or rather match and adjust to each other. Models don't have to stand together (but it gives them advantages), but can be positioned freely. They count on the many possibilities to creativley rejuvinate the tabletop community, also in exchanging experiences for different builds and tactics. On the quiet they hope that certain builds will be playtested, what induces selling more miniatures to creative hobbyists. Through again and again releasing new units and models they plan to take away stagnation and everything is in a steady state of flux. Future editions are not on the table anymore, they could expand AOS as a "liquid system" at their hearts content, like a collecting card game.
When I asked him, if that wouldn't lead to an arms race he put my mind to ease: There would be special editions with limited models, this would include now available but some time discontinued models, which would be especially rare later on. He actually mentioned Chaos Dwarfs (!) in this context. GW will at least provide a Battlescroll for a "core unit". It will cost them nothing and will do no harm. The urge to collect will be fully exploited. But the player who buys and plays the newest models will not simply win, but the player who has the most skill to combine his units with synergy. A perfectly complementary group will have an advantage over new units, which will have to find its role into the existing army through playtesting. I know that my relative has whole cupboards filled with armies and he said, he will look forward to fiddle for hours with his army lists."
