>>53275656It's different now that HMs are gone, but from gen1 to gen5, I felt like grass mons were useless for the main story. You're required to have a water mon for Surf/Waterfall/etc. and water already covers all the types that grass would cover except water itself. So you can pick a grass starter, then capture a water mon which is going to be redundant with your grass starter for most of the game. Or just pick the water starter and don't have a redundant pokemon in your team. Alternatively fire starter + water mon.
