Not anymore. I was shocked when Blaziken was soaring through the levels with the help of the exp. share despite the fact that I never really used it. I finally decided to use it up against a Team Flare Grunt, and it was killed in two shots. It was literally beaten by a level 45 Houndoom. I kind of gave up on it at that point; a level 64 just lost to a level 45? That's totally unreal. I was disappointed, to say the least, but Yveltal has soon since replaced him.
Also, Blaziken is banned in competitive, so to the people who want to use it competitively, sorry to rain on your parade.
