On top of that, you didn't have any decent damage move for the two types that were supposed to be strong against Psychic... and they also made the only Ghost types and many Bug types in the game part Poison so they're actually weak to Psychic :O
Gen 1 had no notion of type balancing whatsoever. Basically certain types were garbage you'd better pretend they didn't exist, while a few others were a power fantasy. Most insulted type was probably Fighting, with their terrible Sp. Attack translated into also a terrible Sp. Defense, their best stab move being literally Submission (lmao) and much less use since Dark and Steel types didn't exist.
