1) Damage
A pure class barbarian using a one-handed weapon (IE any smart player) has aplorable damage. I may only be low level at the moment, but im currently dealing a max of roughly 27 to a combat dummy on a non-crit. Fighting Giants Ogres i do even less (10-12 ogres, roughly 1-10 on giants) whereas other players my level score for 12's and up easily.
2) AB
With only rage as a source of AB boosting, pure barbarians are simply left behind when it comes down to AB. Granted, at low levels we have a massive edge on others, but as leveling builds and item strength grows from +1 to +3 all the way up as high as +7 or +8, rage becomes disenchanting, if not replacable by damn near any mage with half the brains to bring Bull's Strength and Endurance. Once Greater Rage starts capping your Modifiers, pure barbarians can only rely on their feats (for a whopping 4 AB), weapons (for up to 6), and BAB progression (+1 AB per 2 levels... yay?) for any kind of AB boost.
What could be changed to fix this?
Well, I'll start by mentioning the roundabout way of my concept. There is currently a feat only usable by barbarians of 20th or grater level, called Mighty Rage. At the moment, Mighty Rage is pretty much useless as soon as you aqcuire it, as Greater Rage was already very close, if not already capping your bonuses to strength and constitution. The only added benefit of even touching Mighty Rage is that it adds an extra +1 to will saves and doesnt incur an AC penalty for its use.
For all of you out there who don't know me (alot of you) i play on a PvP server called Antiworld CTF. On antiworld, we have changed Mighty Rage to simulate an un-capped strength and constitution boost as easily in as much of a balanced manner as possible.
On antiworld, any barbarian with 21 Con and 21 str may take Mighty Rage, and use it (Stacking with Greater Rage). Before they mighty rage, Greater rage has already capped both con and str. So what is the point of Mighty Rage? On my server, Mighty Rage adds a flat +4 AB, +4 Damage, +4 Will Saves, +4 Fortitude, and +4 HP per barbarian level (only the HP is per barbarian level).
Granted, there were ungodly ways to exploit this to make characters do things with rage that are unspeakable, but if you make Mighty Rage a pure-barbarian-only feat, and added these changes (possibly with less Temporary HP, maybe something like a flat 100 instead of Based on Level?) there would be at least a moderate incline in pure-barbarians on the server.
This helps the damage out a good bit by adding +4, which still wont make us crazy damage dealers, but it will give us a bit more bite than the average joe. The AB boost allows us to raise our constitution to play a more Tank-like role in the group, while still maintaining the AB to hit stuff every now and again. And the HP boost will give us more endurance in battle!
Just an idea to consider for pure barbarians as a boost
