PSA: The Teemoing

Yeah.. although with gals like Syndra and others with lots of CC, if you space it out (and you can hit the skillshots), you can keep them at bay so they mostly can't get to you. Rylai's helps a lot but not sure it's smart earlier than as a 2nd or 3rd item. I went with 15% base cdr from runes, morello then some other items to get maxed cdr, up to 45% with masteries, so I can spam her abilities. Won twice so far with randoms.

This last game I got 18/4/13 (I had a few much worse performances earlier), I died with the Teemo at around 2k HP, not sure if my Zhonya's would have made a difference had I used it. The Karthus on our team died but during his death phase just before fading out he managed to finish off Teemo, probably were going to lose otherwise, big clutch on their part.

Had Morello>Rylai>Dcap>Zhonya's>Luden's, and probably would finish with Void Staff or Merc Treads depending on if more Tenacity and Move Speed would help more, probably not in my champ's case.

Managed without boots though that game. :^)

You can get away with lots of ranged kiting, actually. Mages that can abuse rylai's/liandry's well are darn good. I've been having a lot of fun with Zyra, for instance. It'll cut through Teemo at the end reasonably quickly, with the %HP based damage. I can see that your Swain idea would work well, too.

I've also seen there may be some opportunity to use wave clear to somewhat abuse the bot AI still. They won't tower dive (at least that I've seen), so routing around them and farming the incoming wave behind them can confuse them a bit. Did this with some decent success as Sivir.
