OK, this is not sad at all. Ideally, you'd never have to have more than 4 HMs on the same team (in original R/B/Y Flash was basically useless, so you only really had 4). It's one of the dumbest aspects of the game that you have to either replace lots of precious moveslots or an entire team member just to lug around near useless skills (Surf/Waterfall are really the only 2 you'd ever want on a poke).
In G/S/C, Rock Smash was only a TM (terrible considering you actually used it out of combat), and they added useless whirlpool and (at that time) useless Waterfall (less base power than surf and still special). If they add the fog mechanic from D/P/Pt, I will destroy them, it was the dumbest thing I could ever think of, ESPECIALLY when it didn't completely replace flash as that "useless thing that you need maybe 2-3 times in the game and does nothing special in combat" move.
If they actually have wised up to the problems with previous games, they'll let you use items (like the HMs themselves) to solve those bloody problems and make teaching them optional, that way you can actually use a decent team while playing.
I've always viewed Pokemon as an RPG rather than a kid's game, even though that was its target audience, and I would also have liked to have a more complex storyline. Complex doesn't necessarily mean mature, there are plenty of RPGs with complex storylines that aren't mature: the Final Fantasy series and Chrono Trigger come to mind. Something beyond the typical "Hi, we're evil, no real reason, just evil." That and I'd like to see some actual plot in Kanto. Original G/S/C it was really just 8 more Gyms you had to beat for no real reason, with almost nothing between them.
Bleh, but I'm an old codger, so take whatever I have to say with a grain of salt.
