Might be interesting, but then they'd be so specialized their teams would be much too predictable and easy to beat.
Not necessarily. For example, let's take the Water/Ice example.
At least 2 pokemon with both-Lapras, Sealeo
Now let's throw in Starmie for fighting types and Snorunt for grass types.
Of course it's not perfect coverage, but that's how the gyms work.
What. Starmie is Psychic =P
But okay, I get what you mean. Maybe I'm just stuck in tradition, but I still don't really like that. As if it's just the opposite and they're not specialized enough. Was there ever really a problem with how they are now?
He means that starmie as a psychic type can deal with fighting types... just like snorunt is an ice type that can deal with grass types.
"As I was walking up the stairs, I met a man who wasn't there, he wasn't there again today, i wish I wish he'd go away."
i'd like for gym leaders to be based on something other than types... like one is a dog trainer and the whole gym has things like growlithe/arcanine, houndour/houndoom, etc. dogs may be a bad and limited example but you get the idea. maybe make the gym cats and dogs to have more variation. there's a million other themes you can use in this way.
I understand. I've always wanted to battle gyms that use a similar strategy (rain team, annoying, baton pass, volt-turn, etc) instead of types, but it doesn't look like types are going anywhere anytime soon.
