Pokemon designs, as every gen has proven, are always easy to get used to. Everything like this just takes time
Moves however, i fear Gfreak can't have too much idea anymore other than dishing out more useless but flavourful moves (like tail slap) or broken ones (like shell smash, quiver dance), or clones of powerful moves for all types (Stealth Ice, new 120-BP recoil, new priority)
It's fun thinking of how this and that Pokemon will improve competitively, but if everybody gets the same myriads of powerful options, the metagame can only get more offensive and powercreepy. Smogon will have a harder time pleasing people. Either people complain that the Pokemon they lose to still haven't been banned, or noobs complaining that their favourite overpowered craps have been banned for "no reason"
I can't say I disagree. I mean, considering competitive throws the majority of attacks out the window already, what more do we "need"? A strong physical ice move for those that get ice punch is the only thing that immediately comes to mind.
