Flying, in and of itself, isn't much of an issue. Flight on a monk, well, it's not broken but obviously it's a strong combo. Remember, if a non-flying enemy wants to engage a monk, they must use ranged attacks. If they do, the monk can deflect their missiles.Exactly. You just ensure your encounters feature flying creatures or creatures with ranged attacks at reasonable frequency. Or you set them in dungeons. Occasionally you let your PCs rain death from the sky and feel good about themselves.
In games I run most PCs are flying from late T2. In my last AoW campaign, the Warlock was riding around on a Broom of flying, the Cleric had boots of flying, the Druid had an elemental banner that let him fly (and they could all cast or assume flying forms anyway via wild shape, polymorph, air walk or the fly spell), the Bard would cast Fly, and the Swashbuckler had Lightning and Thunder, paired swords that let him fly 1/ short rest.
And that was at around halfway through T2, approaching T3.
It broke nothing. Beats me why people are scared of it.
A spellcaster is just a bad match-up against a monk for obvious stunning strike reasons and if a monk can match and exceed a mage's fly speed, it's downhill from there.
A high AC frontliner with high dexterity and strength would be the best counter to a monk, but now the monk doesn't have to stay in their reach to attack (fire snakes).
