Simple maybe you can win 1v1 with it on some paper champ, but what if your enemy is a volibear no chance. In other case i think dont buy trinity force and just spamming with full crit attack speed is waste of time, if you wanna do that there are better champs to it like Master Yi his skills can used to be that, but i dont prefer it either.

ummm... sorry but almost no effort was put into this build, no mastry explaintion or runes or anything else except what is there, which isn't enough

I've played eve AP, hybrid, and AD lately. I like AD best. I go Triforce first. Gives you move speed, crit, a little ap for early game, a somewhat slow, and AS. ALL good things for Eve. Somewhere in there I buy boots. I prefer mobility so I can get places fast, but boots are all preference. Next I go infinity edge, amazing crits now. Next phantom dancer, move speed and crits. At this point you have 72% crit without runes, and almost max attack speed with your ult. You can still spam hate spikes so you get constant procs with your triforce when they're ready. Last two items can be madreds for tank killing, or something defense, or black cleaver/bloodthirster for a nice AD boost. As long as you can avoid the tank with oracles, the kills come easily enough with all the crit. I know the abilities scale with AP. But you can really play Eve AP or AD.

why not try tri force? give you crit, as, ms, and awesome dmg, always works good for me

i like the asp :D it's awesome

I agree, AP eve is so much better. DPS eve just plain sucks late game. With my eve i could pretty much kill any non-tank character before they even get a chance to run because i have like 600 AP which is added to my attack damage because of lich bane, and ravage and hate spike will deal considerably high damage.
You should check out my build:

wouldn't a sheen be ideal for this build because you hateful strike every 3 seconds for the damage boost?

A better item for fifth slot would be a MALADY, gives 50% attack speed and 15% life steal

Hmm, not really. There's Sword of the Occult;

+10 Attack Damage UNIQUE Passive: Your champion gains 2 damage and +2% critical damage per stack, receiving 2 stacks for a kill or 1 stack for an assist. This effect can stack 20 times; you lose a third of your stacks if you die. At 20 stacks, your champion's movement speed is increased 15%.

Or Atma's Impaler

+50 Armor +18% Critical Strike UNIQUE Passive: Physical attacks deal an additional 2% of your max Health in damage.

Not really the same tho.
