Eh, where I'm at, people will let you walk right up to them. I generally get a chalice or Sightstone as my first item, then build boots, or a Sightstone if I started with a chalice. Alistar is probably the only champ right now that I would feel alright with taking into ranked. I'm just so comfortable on him that it doesn't matter if he's the best or not. If it's one thing he needs, though, it's cooldown reduction. If Riot decreases the cooldown on his Q and W, that would be a major buff by itself.
I'm Slayr231, so I'll add you!
I saw the video, but didn't realize that they added him on the PBE. I don't play on there, but I watched a video of his abilities. Seems really cool, and it looks like we might have another assassin to watch out for.
