Thoughts on my Twitch itemization

So, I usually go heavy/full crit. I haven't played in a while, but I was looking at the new items, and when I play, I would most likely build (not in order) phantom dancer, runaan's hurricane, essence reaver, infinity edge, bloodthirster and mercurial scimitar. I'd end up with 100% crit and +280AD, and crit damage doing 50% more. I'd be getting mana return from essence passive, as well as cooldown reduction. Decent life steal, a lot of attack speed, some movement speed. I'm looking for legit honest feedback from people. I'm not a serious player, but I don't want to be missing out on what I could/should be bringing to match.
