I don't like Sated Devourer -- Here's some Yi Math

Lets look at how many attacks Master Yi performs between Alpha Strikes with both the regular and sated versions of devourer:

Master Yi with 50% attack speed from devourer level 18 attacks 1.25/s, and Alpha Strike will have a 14s cooldown

With Regular Devourer: Alpha Strike, 1, 2, 3, 4, 5-6, 7, 8, 9, Alpha Strike Alpha Strike, 8 real attacks, +1 bonus attack, Alpha Strike takes 6.5 seconds with 9 seconds reduced cooldown.

With Sated Devourer Alpha Strike, 1, 2-3, 4, 5-6-7, 8, 9-10, Alpha Strike Alpha Strike, 6 Real Attacks, 4 bonus attacks, Alpha Strike takes 4.8 seconds with 10 seconds reduced cooldown.

As you can see, Master Yi with Sated Devourer applies on-hit effects 10 times in 4.8 seconds vs. 9 times in 6.5 seconds. He additionally performs alpha strike 26% more frequently. Not only that, but Wuju Style lasts 5 seconds, so he can only do 6 full attacks with true damage before it wears off, and then he takes a hit to his AD ratio, so the last two attacks when using regular devourer are missing out on 10% AD + true damage. Let that sink in for a second: He gets 10 full procs of true damage using sated vs. only 7 procs of true damage and then 2 attacks of actual reduced damage. It is also highly possible that his 2nd Alpha Strike will be weaker, too, without sated devourer if he has any CDR to account for input lag.

This is just one example, and the more on-hit effects you add, the worse it gets (i.e. BotRK).

The end result is basically that champions like Yi, Xin, Shyv, etc. get amazingly increased benefit from sated devourer. I think it should be curbed. Severly. Maybe removed. There is no other item in the game this strong, especially for this cost, and for good reason.
