Now consider a party of 2 clerics and 2 wizards in MP facing a larger group including 3 spell casters. This is where is gets clunky. SP 1 wizard vs 1 another caster isn't the issue
Sorry. I'm on their side with this one.
Party of 2 clerics = 2 reactions maximum during each round, and that's only IF enemies trigger AOO. Not very disruptive.
Party of 2 mage's = maybe Counterspell Reaction or Shield or Absorb Elements replacing AOO as their reaction each round because why would you AOO with a mage if you have those spells.
It's really not much different from a party of rogues or fighters. You'd have relatively the same reaction counts.
