What's actually different with unchained barbarians compared to the old version? From what I understand, there's been a little bit of rebalancing (better trapsense thingy), better wording of some rage powers etc, and rage has become easier to use. But are the updates actually good stuff?
Unchained Rage:
While in a rage, a barbarian gains a +2 bonus on melee attack rolls, melee damage rolls, thrown weapon damage rolls, and Will saving throws. In addition, she takes a –2 penalty to Armor Class. She also gains 2 temporary hit points per Hit Die. These temporary hit points are lost first when a character takes damage, disappear when the rage ends, and are not replenished if the barbarian enters a rage again within 1 minute of her previous rage. While in a rage, a barbarian cannot use any Charisma-, Dexterity-, or Intelligence-based skill (except Acrobatics, Fly, Intimidate, and Ride) or any ability that requires patience or concentration (such as spellcasting).
The rage gives a +2 bonus to hit and damage, and a barbarian with two-handed weapons would if using the standard rage strength bonus get +2 to hit and +3 to damage... Also, the strength bonus would give the raging barbarian a bonus to breaking doors, pulling up someone hanging by a rope from a cliff, pushing a heavy rock out of the way, swimming, climbing etc.
But then... The temporary HP is a life saver.
What do you guys think, what are the pros of the unchained barbarian?
