Basically, I'm on a pretty decent losing streak/ streak of games where I do bad. Yes, I have games where I get positive K/D and lots of assists, but I never really have had the feeling where I am dominating for a while... the funny thing I noticed, is that whenever I play 3s, I get matched with level 30s who are experienced and have 600+ wins. I am not as experienced, and since I sucked and had a 10 fps computer (not anymore of course) when I started, I only have about 200 wins. I really need some advice to get back into LoL. I always end up just getting dominated by a better player and making too many mistakes... or maybe it's just the matching thing or the fact that TT is so screwed up.
HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!

I'm not sure what to say. but keep practicing o.o if your rusty.

Know what I hate? When people get pissed about k/d when you're in a long game. Going 40/39 does not mean anything >.<

When playing TT you want to go with a tanky DPS champion with lots of CC. Unlike SR, you are going 3v3 instead of 5v5. Thus, usually in SR we have only about 1-2 tanks. But in TT you should have everyone being a tanky DPS. When playing, always ward the red buff. That's where most people gank and thus you will have vision of people trying to gank. At the start of the game you either want to go to the enemy's red-buff bush or the bottom lane bush. During gameplay, if you are solo topping make sure to gank bot as much as possible, and also one of your teammates should buy oracles or vision wards to make sure the enemy team doesn't have much sight.

Wriggles is one of the most useful items in TT cause it reduces clear times on dragon and camps + the free ward. Also, lee sin is arguably the best champ on that map
