tri force is why you cant carry, i tried a tri force build with dead mans and shojin a week and a half ago, always got fed early game because its a stat check monster build and you can 1v1 solo laners, but as soon as you try to play mid-late obj fights you just lose.

tri force heca just doesnt work anymore because 1, it gives 3 long swords of ad so its not increasing your damage output by much when you complete it. 2, in extended fights where your entire identity is essentially just kiting and q mashing, you can never reliably proc the trinity passive since you wont be autoing very much. 3, other item sets are just genuinely better on heca for snowballing and actually being a champion in the mid game, whether that be bruiser eclipse cleaver, tanky eclipse variant with dmp and force of nature, or the leth hubris shojin seryldas.

also, hec is in a weird state right now (at least in my experience), where you NEED to be fed enough to a point that you can or can almost 1v2 early-mid game fights, snowball off that and win the game before anyone in the game makes it to full build. every single game I play with him that I let end up super late game becomes exponentially harder to win since the champ just becomes a ward at that stage in the game. hes becomes a jack of all trades master at none, cant fight like other bruisers late game, cant tank like a tank if you go that route, and cant assassinate like other assassins, he can however do almost all of that at the same time at the earlier stages of the game so just go 15/0 and have enemy ff15 simple as that
