Im a Lee Sin player since a long time now but i never paid attention to what Masteries i needed. I just based myself on guides that had great feedback and it worked pretty well. I tought that it wasnt a big deal that the masteries had change, i mean i just took what looked similar from the guide i based myself. But i just did a game yesterday and never made worst, it was like if my i was weaker and my dmg decreased by far.
If any Lee Sin player could help me with those new masteries, im sure it would help some other LS player at the same time other than me. ^^
