At 10th Level it will not hurt if everyone in the Party has a +1 armor except the following:
You got dex 20 characters
They got +1 *item* of protection already
Most or all of them use shields
A +1 chainmail for the cleric is fair game
A +1 studded leather for the rogue might be tough already.
Do not give out +3 AC items unless you are well prepared to counter that somehow. It feels totally odd if three Players with AC 15-20 are getting their share from mob physical damage most of the time, but the guy with AC22
is missed even when the enemy casts bless.
