You've gotta also account for armor and any other masteries/runes on both players such as armor pen, reduced champ damage, increased crit damage, etc. The math isn't as simple as 49/88. In fact, the game currently handles the crit as being +100% not 200% of what it should be (yes there is a difference).

If it were indeed cutting off a flat % without any other math involved, it should be saying 93, not 88. (49 + 90% of 49)

So until a red clarifies, we may never know. Even if its doing something as trivial as cutting off 10 flat damage (and worded incorrectly as a percentage when it isn't), thats still way better than a fair deal of the masteries in that tree as far as mitigation from champs goes. 2 points off any champ damage (2 mastery points), 3 points off champ auto attacks (1 mastery point with 2 invested in the previous one), 5 armor (3 points), etc. Heck, even seems better than the final mastery against a fed adc since you're only covering 3 points to every 100 damage with it.

I'm sure some nerd will eventually take the time to pick apart every single calculation and back it up with spreadsheets showing the true weight of the mastery. But until then, all we can do is guess. I for one think I'm going to take this mastery more often than not purely because adc's are the hugest pain in the ass mid/late game (especially when being your teams initiator/tank).
