Honestly I find it hard to get people into the game as it is, without it being more complex. For your average person, AoS is an incredibly complex game with hundreds of rules and stats to remember. Certainly everyone I've tried to introduce it to has said that they found it very difficult to understand. If AoS wants to be inclusive to new gamers that aren't already of the "1000 page rule book gamer" type, I personally think they shouldn't make it any more complex than it is
To be honest that mostly seems to be due to the sheer amount of rules connected to a given unit combined with the amount of units and is not something you're ever going to get rid of in a wargame I guess.
If all they had to remember in their first game is the base rules and some basic concepts like "archers shoot", "guys with shields are for defense", "guys with giant warhammers are for offense" and "that wizard can cast either arcane bolt or mystic shield" it'd be straightforward enough to get a feeling for it, even if stuff like damage profiles would initially scare em. But this not the case. All those units have special nonsense.
For fun all the "special" unit rules in the first AoS box:
The SCE have:
Liberators: sigmarite shields, lay down the tyrants
Retributors: Blast to ashes
Prosecutors: Have a ranged attack (but no clear ranged weapon). Fly. Heralds of Righteousness, paired celestial hammers.
Lord relictor: 2 prayers
Lor celestant on dracoth: Inescapable vengeance, Intolerable damage, storm breath, lord of the host
Then the followers of khorne:
Bloodreavers: Icon bearer, Hornblower, Fenzied devotion, reaver blades
Blood warriors: No respite, gorefists
Khorgorath: Horiffic predator, taker of heads
Bloodstoker: whipped to fury
Bloodsecrator: Portal of skulls
Mighty lord of Khorne: Collar of khorne, reality splitting axe, Gorelord
Then there's also the fact that all captain models in a unit have a special bonus, which frequently is just +1 attack, but not Always so you have to keep track of that as well.
That's what, easily 20-30 special rules on top of the base-rules
in a starter set. I don't think we're going to have to worry about some aditional base rules chasing people off in terms of complexity. The warscrolls will have already chased those people off looooong before they even read the baserules
