>>18880112Something people often don't think about when they say "I WANT MOAR DUAL MOVES" is that you have to take some care to balance them.
Flying Press works because there's no type vulnerable to flying that is also vulnerable to fighting, and there's no type vulnerable to fighting that's also vulnerable to flying. So it's not that good, you're not going to get a ridiculous 4x damage with it unless you're using against fighting/dark types, of which there are just 2 in the game.
But if you take a move and give water/ground typing, you get a move that's 4x effective against all pure fire and rock types; 6x effective against rock/ground, rock/steel, fire/ground, fire/steel, fire/electric; AND, if magcargo wasn't fucked already, muddy water would hit it for 8x damage.
Things get broken easily when you toy with dual types.
Though they could have changed some things, yes. Solarbeam could easily be Fire/Grass.
