Is Infinity Edge a bad item on Rek'sai?

Hey dude. I'm sorry you got downvoted a little bit for this. It is a legitimate question, but a lot of people are making good points on this topic already. IE is not a really good item on anything but ADC's or Assassins who are also building AS/Crit chance to make that damage scale and be relevant througout the entirety of a fight. Given that Rek'sai is a melee AD champion with limited mobility, she will not usually be able to output enough damage to take out carries or frontlines without getting wrecked in the process, particularly given her ratio's have been reduced quite a bit since her release, meaning her abilities can't make much use out of the 80 AD it provides.

Right now, she will be best at building one or two damage items ( are my favorites) and going for tanky items for the rest of your build (full tank can work as well, but you are mostly a utility/knockup bot if you go this route). This is how it typically works with fighter champions as they usually have decently strong early games, but they fall off in the late game if you aren't fed as they will get blown up by cc, mage burst, and ADC's before you can get your damage off if you build mostly damage items.

Keep it up. Good luck in your games. And have fun. Peace.

The only reason ranged carries (and Yasuo, Jayce, etc) can build Infinity Edge successfully is because they can successfully get off multiple auto-attacks. Rek'sai I feel isn't going to successfully get off as many in a fight and should rely on ability damage and sustain to be able to disrupt and kite during team-fights or skirmishes. Also, Critical Strike scales with Attack Damage, Critical Chance and Attack speed which she does not build a lot of in a typical build so it might be a wasted stat. Hydra seems the better choice here.

Infinity edge and crit scaling in general is for glass cannon dps champs. Best on ranged champions or champions with assassin like mobility. The average bruiser champ will get melted in teamfights with a build like this and will unlikely survive long enough to kill the frontline or dive the backline.

Rek'Sai has mobility but tunnels are very telegraphed.

Rek'sai should never build IE.

She needs to build tanky because she already naturally does good damage and she is in the middle of the fight every time.

I've seen squishy Rek'sais and man. They're worthless past 15 or 20 minutes.
