TB is so easy to kill is not funny, only ice TB can actually keep up, with a fire TB after the first round he ends up with an empty gun that cant even run well, maybe rook can have trouble but come on, really TB OP?.
I really cant belive that people say a character is op simply because they dont know how to kill him or because the enemy selected an strategy weak against them, is like an ub claiming rook is op when he goes completly speed and atack and dont get life steal or some armor, think a little adapt and use your enemies weakness.
About Oak vs Tb, it will split him in half he just needs to keep his ghosts back while the tb fires his first round after that move in penitence+surge of faith, basicly a Tb needs to be intelligent to survive 1v1.
Theres big mistake noobs make against TB, if you are fighting against tb, DON'T but priests, angels i dare say catapults, if you dont have enough to go for giants simple dont buy them cause you are just feeding him he will go lv 20 so fast you wont get a chance specially around lv9-11
