Personally I prefer this Fire main / Tobi meta more than what'll will come in the future with the Tanky/Evading Earth/Water stuff.
This one has more counter-play, everythings bursty and squishy. Just take out the linkers i.e. Kakashi/Sasuke/Fire main and it crumbles, you can even do it with Battlefield 0 CD skills and characters, like Wind main hurricane skill (extra effective vs Kakashi/Sasuke lightning).
Anywho, just have to wait for Tobi nerfs regardless, Tobi mystery no longer KD (i.e. he doesnt chase himself) and he doesn't revive. I don't think its necessary but whatever.
