Be prepared to have everyone hate you when you play Teemo. He's hella fun though.
Everyone as in enemy, or everyone as in everyone, and why? lol
So far from what I've been toying with I like getting my icy mallet first because it makes it hard for people to escape my doom darts, and it also makes it a lot harder for people to gank me easily because of the nice hp pool, as well as being able to slow down people chasing me. Usually go for other stuff first but lately it keeps putting me against certain bots that like to pew pew with long range ults. seems to be enough to keep me alive, but again, that's also vs bots. A lot of what I do for builds is very similar to some of the build guides I've already seen for Teemo (long before I even knew of said guides) so it seems i have my brain in the right place for some things. I'm still getting the hang of how different champions interact with one another (like knowing which ones have me beat out in range and by how much, things they do that will mess with me so I know how to build to compensate for them, etc...) So far I know that Lux, Miss Fortune, and Ashe can make life terrible for me, but have started to figure out ways to make it less terrible...
(Longer post than I had intended... long story short though, finding some people I can play with and/or against even if just in custom games to work on skill etc would be spiffy. Also, not sure why everyone would hate a Teemo player <_< )
