Yeah, some mechanics had wonky programming (focus energy halves your crit rate instead of doubling it, just to name a few) and some design choices were completely borked (Dragon is weak to dragon but the only dragon type move is dragon rage which does a set amount of damage lol)
Everything about Psychic - Bug - Ghost was broken in gen 1... and then Dragon. Wtf was that? Dragon Rage? Really? When Ice beam is a better idea for Dragonite than a STAB move, not to mention the whole special vs physical aspect, the shit's broken.
Also though... I think they overcompensated for Dragonite in later gens; Extreme speed on a Dragonite is just mean.... upon whatever the Dragonite is attacking. (By using Extreme Speed you can ignore investing in Dragonite's speed and buff his HP instead... plus use Aqua Jet if you have to, and you can then either go DD and weakness policy or just choice band it, lock yourself into ES and skip the buff turn). fUcKiNg MoNsTaR.
Oh, and if you can get a Gorebyss or a Huntail that you had he patience to deal with leveling up to 50 for Shell smash, you can baton pass the shell smash to a Dragonite that has HP investment and a focus sash and instead of going with a band or a weakness policy, you now have the best physical sweeper in the game so long as you can avoid ice shards. That's really hard to pull off though, as more than likely your putting the focus sash on the baton passer.
One last thing, the most effective way of dealing with a focus sash dragonite is just to deplete it's extreme speed PP, but that's easier said than done. Ghosts and spiting it work, but that's why aqua jet is there... and as it's sashed and not banded, it's won't lock itself into a move. The second best option is hoping toxic spikes stay up upon the switch in, but guess what? Clamperl learns Clamp, which is going to mean they can sacrafice the Gorebyss or Huntail and switch into something can rapid spin that threat away, meaning instead of outright solving the problem, you're now playing a game of switches. Oh and whirlpool and aquatail, also adding to the fucked up game of switches.
(I mean gen 1 was fundamentally broken but at least it was FUN)
