Teemos buffs they mentioned will not help his laning phase at all. Unless your like rushing Zerker Greaves or Malady or something. Then it will be a slight buff to your laning at the cost of not getting a Phage early which is not what you should be doing anyway.
They're aiming at buffing his late game for good reason. He falls off a little bit. Altho I'm betting the buffs to W and R will be pretty meh and bug fix will be the big change.
