XD Well, Garchomp happens to do it better, simply because I'm pretty sure he's faster than almost anything OU (Except, like, Ninjask, who doesn't hit all too hard) and he has an excellent movepool. n.n Trust me, it does make sense.
About the Wobbuffet, though... Yeah, it makes sense not to hit it until you need to... But if you just start using Stat-upping moves, or things that don't hit, then it can just Encore you, then switch out into something that'll kill you while you're helpless, trapped in Encore. o__o
And finally... Well, I know where you're coming from, but here's the thing about luck:
I once had a match where a Vaporeon in PBR double teamed once. After that, absolutely nothing I did hit it, and it swept my team. Even when I double teamed back 3 times, it hit every single time.
Can I say I lost because I wasn't skilled enough? Nope. Do I know what I have to do it make sure that doesn't happen again? Not at all. I lost because of random luck. (It was the 85th or so fight on the 100-battle-marathon thing, too.)
This is why they try their best to take out things that rely on luck for winning, because then it's never clear who trained their Pokemon the best, or who predicted their opponents moves best.
See what I'm saying? Double Team, Bright Powder, Focus Band, where you randomly hang on with 1 HP... You never know when they're gonna kick in. And if they kick in at a place that completely screws you over... Well, what would've happened if it didn't? You just lost because of luck, and that's just crappy.
...
I also hate luck items because I tend to have to worst luck, too. XD; So, I'm one of those examples that always get messed up because of it. >__>;
