Welcome to my very first guide.
I'm not a very skilled player, but i love TT and a few people publish guides focusing in 3vs3.
Just read it and don't hesitate about giving your opinion,Everything that can help is welcomed.

Pros: Cons:
-If fed, unstoppable -Weak at early game
-Lot of dmg -Weak to stuns
-Good passive when pursuing -Low survavility( Glass Canon)
-Focused

At the beggining focus on last hitting.After you reach level 6, it rockets and you should start cleaning the jungle with ease.
Even if you're fed and winning don't forget to farm, you don't know what is about to happen and the better equiped you are the less it'll cost you to win.

Nida is know for it's balance and large set of skills, allowing her to be ad/ap/hybrid and ocasionally get tanky ( i don't reccomend so).
The biggest problem should be aiming with the "Q", skilled players dodge easily long shots. I reommend shooting behind walls so they can't see it until it's almost hit 'em.
The "E" is very useful ( This is the reason why i buy 2 mana potions at the start).
And the animal skills are just devastating.
