If Rotom-I is the refrigerator one, it kinda sucks

All of Rotom's altered formes have defensive stat spreads, thus the ones with the most/most useful resistances (Rotom-Heat and Rotom-Wash) are the best. Electric/Ice is pretty awful defensively, weak to Stealth Rock (Rotom switches in/out a lot), plus the common Rock- Fighting- and Fire- types, while bringing no resistances to the table that Rotom-W/H do
