you don't need math to know that built 1 deals more dmanage, though it should come with cdr/lvl glyphs
Iceborn is always far less damage than trinity, Bc is less damage than LW, and trinity+iceborn means iceborns spellblade gets lost vs the main target(aoe and slow still aply while trinity is apllyed vs the main target), makeing it a near zero damage item.
Also, if you really want the most damage:
, not as great for midgame pokeing, but the raw damage potential is way higher.
but for blue-builts, your build 1 is highest damage, built 2 is max utillity(though you can get other boots, icenorn+bc are already 30%, it's better to get the last 10% cdr from runes/masteries) and works best for kitecomps with alot physical damage, while the same built with cd-boots and LW instead of BC would offer more damage, but less tankiness and selfish armorpen rather than a shred for the whole team.
Also, I'm not a fan of
, it gives bad stats for the gold, and most of the time, if it gets proced, your enemies have won the fight already and can just wait around till you revive and slaughter you again.
helps alot to not geth cought by random cc or bursted by ap,
is way underated on adc if you don't have iceborn. especially on EZ as it works on Q,
is great if your main problem is getting cought in cc and are confident on remembering the active in time.
, way underated on adc as def item vs burst, the base damage works with Q and trinity, but mostly it gives the most effecktive hp off all items vs burst.
If the shield gets proced, even on an adc you usually reach 2500+hp with it, meaning a 750hp shield, so 500hp+750shield=1250effective hp vs burst, with hp seals and trinity or BC, it gets even better.
Or just ad another off-item, especially
, if you don't die to fast in the fights.
If you don't get bursted or chain cced, the 20% lifesteal actually can give more tankiness than any other item, while also offering alot ad.
On EZ, i rarly get a tank-item as he is very save with the Q range and his E.
