Pyke Passive AD Conversion Ratio

Okay so starting level 1 Pyke has 66 AD, if you buy a Warmogs which gives 800 health you then have 124 AD, then if you subtract the starting 66 AD we can see that 800 health transforms into 58 AD so you get 0.0725 AD per health point

At level 18 Pyke has 109 base AD and with the same Warmogs test he only sees a 57 AD increase or 0.07125 AD per health point. The ratio goes down.

Conclusion: Building health items on Pyke with his current conversion ratios is ineffective and you would be better off building straight AD
