You miss my point. I know I can evolve him earlier, but in case you haven't noticed, he learns Crunch at 39, Outrage at 43 and Flare Blitz at 45. Outrage can be tutored in post game, the other two can't.
And as for Volcarona, why would I ever use a pokemon whose only good attack for 90% of the game is a Bug type one? o.o I fail to see the point, really.
