The main complaint is spamming numbers 1-9. Auto-attack isn't going to fix this. Anyone who has played current MMO's like WoW or Rigt know you are just hitting number buttons wait for a cooldown. Auto-attack is nothing more than a mob clainming system with minor DoT in these games. Make sure you understand what you want instead of just a blanket statement of Auto-Attack. Do you want fast or slow paced combat?
