>>12003653That's tricky, because Dragon is essentially not Super Effective against anything. Steel is one of the best defensive types, allowing both stall and hyper offence to survive. Remove Poison, and you buff Stall. Remove Fire and the metagame becomes entirely Physically oriented. Remove Electricity and what was once a balanced meta becomes the Rain Dancining. Remove Normal and you remove a defensive Dragon type, not really weak or strong against anything. Remove Grass and Rain teams get super buffed while Sun teams fall completely out of use. Remove Rock and you remove Stealth Rock, and Sash set up sweepers will reign king. Remove Bug and you lose out on some great coverage, especially for Psychic types.
Really, removing anything would hurt the meta more than help.
