i was facing against a garen and ezreal as eve so i build raundins omen first but then i realized how much magic damange garen and ezreal do it seems almost like they do more magic damange then ad so i was wondering if i ever face against a garen ezreal should i build mr first or maybe i should go spectrels cowl then wardens ? any thoughts
Well, they're doing more magic damage because you built armor, reducing their physical damage greatly.
Not to sure about Ez, but for Garen a chain vest into health is the best route for reducing his damage (which you did, good job). After that one magic resist item of some kind should be bought to reduce his ult damage, hexdrinker being the absolute hard counter (wait till end game to upgrade). If you buy too much armor, Garen's black Cleaver becomes more and more effective, so I wouldn't go crazy on that, but Garen has no way to deal with magic resist rendering his ult near useless and weaking the damage of sunfire if he has one.
You need 100 armor for every slice of 750 physical damage you absorb beyond the first slice. Same for mr. This take into account the gold efficiency.
For exemple if garen makes 75% physical AD and 25% magic and you have 2500hp. You'll receive 1875 physical dmg (2.5 slice of 750). So you'd need 150 armor to be optimal. And 625 magic (.83 slices) so you still dont need any mr.
Hope it help you balance between mr, armor and health.
