Works great. If you assume "AD carries" are a homogenous group than only ever have basic AAs, and no-one else appreciates both AD and AS.

If you think would benefit as much from one of these high AD/AS items as  then you need to take a closer look at their kits. Similarly if you think or  for instance would get the same benefit from chucking one of those into their builds than they would from one crit item...

It would require a MASSIVE balance overhaul on a LOT of champions. Some bruisers would do well out of it. Others would find it useless. Some assassins like would do quite well out of it too, whereas  wouldn't appreciate it nearly as much.

AS and crit are just not comparable. If you scale with attack speed at all, you benefit from building even a little. If you want to benefit from crit, you really need to stack crit items because even a sole isn't that great if you've got no other sources of crit chance - kind of like getting  if you've no other AP. You can't replace multiplicative scaling with flat scaling and expect it to yield the same results.

I mean just look at what did for champ balance. Meant to be a counter to health stackers, now a staple in many builds regardless of the enemy team. That's what happens when you meld attack damage and attack speed into one item.
