I was never a fan of Chimchar/Monferno, and I got banned because I bashed it.
Now, it's not the best Pokemon and I don't love it, but I can live with it.
And personally, I don't want Monferno to evolve in the League, but I think it will.
And something that makes me a little mad at somebody, is that they want Monferno to get more and more screentime, and he already had enough. It's fine that he defeated Fantina, but they could have made Staraptor take down Candice.
And against Volkner, the four, Monferno, Pikachu, Grotle and Gible is a must I think. But if they make Volkner get 5, it's hard to choose between Staraptor and Buizel. Both can do well.
