no triforce on nasus?
i cried inside. get a triforce instead of a frozen heart next time and you're golden
At most, nasus needs a sheen. Early-game. Triforce is a waste on him. It gives him attack speed (which he doesn't need) attack damage (which he doesn't need) crit (which he doesn't really need) ability power (which he REALLY doesn't need), a slow proc (which he doesn't need) and no CDR or tank stats other than some health. Admittedly, the movement speed is nice, but hey - Wither. And he already has ghost if he really, really, really
wants to catch someone.
Frozen heart is far better on a nasus that can farm. - he gains from every single one of the stats - Mana, Armor for tank, CDR for more Q spam (CDR is far more effective the more you have, considering his reverie that 20% cd gives him way more damage, and he has the attack speed aura to boot. On top of that, his build gives him plenty of HP already, so the defensive stats of the FH are compounded - while a trinity would just add another 350hp with no extra mitigation. Seeing as most of the entire enemy team is AD, he likely rushed the glacial shroud to stay strong in lane (likely against Tryndamere or Warwick, if it was tryndamere even better), which is a very good idea.
If you really wanted a triforce on that nasus, he'd need to finish the randuin's, then sell the aegis and get a full tri-force at end-game
, which this game was nowhere near. At that point, it's even more arguable that if he kept farming, a triforce would be needed even less, because the bonus dmg from tri is flat while he can keep farming Q.
Buying a trinity force on nasus is like buying ~50CS for your Q. It's pretty silly. CDR is far better for near 90% uptime on wither, more Q farming, and more Qs overall.
tl;dr, sheen and triforce are respectively paying 1.2k for 20-30cs on q and 4k for ~50cs on q, far better to get more tanky and CDR at all points in the game.
