My thoughts are that when you do the math, factoring in critical strike chance, just the bonus damage of versus that of  is a 25% increase on the side of Tri-force.

Aside from that, Scales of AD which Tri does grant and IG doesn't. His Q is also able to Critical strike, which makes Tri even more valuable over IG. Yi also has a double strike mechanic that applies on-hit effects, giving you double chance to proc phage.

And on top of that, Tri gives mana too... Are you really willing to give up 250 Health, 30 Attack Damage, 30% Attack Speed, 10% Critical Strike & 8% Movement Speed for 300 more Mana, 70 Armor and 10% CDR?

The only reason to get IG is the AoE damage, but Yi has his Q, so that's not really an option.
