3-3 would be so annoying and time consuming. this better be fake, going overboard
It's not fake.
I think it's a pretty nice idea. I mean, DP threw us into the physical/special split and we've learned to cope. Of course, some of our favourites got severely dented in the process, but along came many advantageous boosts. We shouldn't be so quick on the draw and shoot bullets at blurry targets. First, we should probably learn how it's going to play out. For all you know, there could be a whole different system when it comes to 3-3 battles. I mean, all we have to judge upon right now is a sole trailer/image. We haven't even seen it in action, people.
I think that the whining (or, 'opinions,' if you prefer, but if you do, they are rather prejudiced) should be minimized because we don't even know how this will play out. With double battles came new moves such as Helping Hand, and with triple battle will arise moves based on triples.
Nonetheless, I've always favoured battles featuring more than two pokemon at a time, as it causes the battlers to focus more on strategy than raw stats and movepools, which is why I've always wondered why single battles were so focused on. And of course, adding more pokemon into the fray will only increase the strategy play, which I see as beneficial. Also, yes the screen will be a bit more cluttered, but I foresee the health bars going horizontally, as stacked would just cover up the opponent.
Maybe you all don't like certain things happening (such as an earthquake nullification, as said earlier, I believe) but there will obviously be new features to compensate for losses.
Game Freak may be risky, but not stupid, after all.
