If you had the chance, how would you recalibrate the Pokemon typing chart to make it more balanced? For example, Ice is probably the worst defensive type, and Poison and Normal are probably the worst offensive types. I was thinking Poison should be super-effective on Water, Water should resist Fighting, Ice should resist Dragon, etc.

Oy vey.  Okay, I don’t pretend to have thought through this in any great detail and I promise I will someday do a whole entry on this, but I don’t believe any of these changes would break anything…

– I probably would throw in Poison-beats-Water and Ice-resists-Dragon; maybe not Water-resists-Fighting, though, since Water is a pretty good defensive type already.
–  Some of Steel’s resistances need to be eliminated; I think Ghost and Psychic are reasonable.
– Bug used to be super-effective against Poison; I don’t think it would hurt to make it neutral now.  Grass has more offensive weaknesses than any type in the game and I don’t think it would be unreasonable to make Grass attacks neutral to Bug or Flying types (or both).
– I’m tempted to say Normal should be super-effective against *something* but I’m not sure what yet…
