Currently, this feat is essentially making barbarian splash builds viable by extending rages to a reasonable length. The extra 4 str/con is definitely over the top, but the main reason people chose this feat is for the extended rage. When this feat does get corrected, would it be possible to change the description to read:
It seems odd, but correcting this feat would take it from being a must have for any barbarian splash build, to a niche feat only desirable by intim tanks. I would hope it remains somewhat useful to the builds that currently use it.You gain +1 hit point per character level, have +2 to your Intimidate skill and can enter a barbarian rage once per rest, or increase you current number of rages by 1 use per rest
