On to the Codex rant. :)
Alllies are fun but break the game, mini dexs ( looking at you Inquisition ), will further plunge the 40k gaming universe into a build this list to win. Comp will be introduced to most GT's and RTT's if this escalation continues. Think I'm joking? ask any army now being able to include psycho-broke grenades for under 75pts( in addition to stubborn and Divination ) in a unit. Tyranids will break the back of the nid players or gut the meta once again to a degree no one saw coming. No allies, but have to compete with armies that can take 3 different allies ( example: Space Marines, eldar, Inquisition ). Let me back up when I say break the game. It started as something fun and cool to run allies. Than turned into the exploit every asset and decrease any weakness. Its now 2000 points of death star kicking teeth in Vs playing to your strengths. Now you just list build out any weakness. The biggest/baddest death star currently is the eldar farseer thing. Well take away allies. Still very potent, but way more armies can deal with it. The Demons are more manageable, but look why? no one can join them! Even battle bros! I agree 2+ re-rollables are dumb and a major mistake, but it's the allies that are the final straw to a bad situation to begin with. OK done !resume wish listing and posting it as fact :)
