[GAMEPLAY] Master Yi crits less than he should

Almost a year ago, there was a post on Reddit demonstrating that Yi does not crit as often as he should. Specifically, the first hit of his double strike and the next hit after will almost never crit. The hit before double strike, the second hit of double strike itself, and his first three hits before double strike activates can all crit normally. I went into a custom game today and played around for about two hours with lots of different builds and situations.

In summary, building only zeals and crit cloaks to reach 100% crit chance, every hit was a crit. However, upon activating highlander with these same items, I noticed that my crits were significantly reduced. Furthermore, building a complete phantom dancer with 100% crit chance reduced the number of crits significantly as well. Finally, building a full static shiv with 100% crit chance reduced the number of crits, but not by as much as the phantom dancer.

Here is all the data that I gathered:

70% crit, no PD, no highlander crits: 18 non-crits: 13 total: 58%

70% crit, with PD, highlander for 7s crits: 23 non-crits: 28 total: 45%

90% crit, with shiv, no highlander crits: 32 non-crits: 15 total: 68%

50% crit, no PD, no highlander crits: 25 non-crits: 16 total: 60%

100% crit, no PD, no highlander crits: 29 non-crits: 0 total: 100%

100% crit, no PD, highlander crits: 10 non-crits: 7 total: 58%

note: only 50% crit chance during the 7s of highlander after first 3 hits

100% crit, PD, no highlander crits: 23 non-crits: 17 total: 58% note: first 3 hits always crit, 2nd ds hit and hit before ds always crit, 1st ds never crit, hit after ds only crit once note: same result w/ highlander

100% crit, shiv, no highlander crits: 15 non-crits: 3 total: 83%

100% crit, shiv, highlander about 70% (forgot to record)
