Why is Set Mode recommended? I hate being at a disadvantage if I can avoid it.
The thing is, in Pokémon you're already at an advantage anyway. Opponents are in set mode, rarely switch, and almost never have as many Pokémon as you. Switch mode is trivialised by a set of glass cannons because of the free switch, where as set mode actually needs you to consider what Pokémon can take a hit switching in, or how to maximise coverage on each individual.
