I was actually working on my TR version of my main and got off on a tangent looking at the berserker set bonus. This build is designed for buffing/tanking in shortman groups or for speed runs where bard buffs and extra dps is needed. This build is layed out for powergamers but can be adjusted easily. I am only listing the pertinent information, the rest doesn't matter.
Warforged Skald V3
14 Bard Warchanter 6 Barbarian Berserker
[42/44]18str +2rage+9item+4tome+1lotd+6rage+2frenzy+2madstone

V3 means double reincarnated. For 28 points builds or first few times thru, drop str and/or con down 2 points to compensate.
Rages: 6
2 barb levels 1 and 4
1 warchanter I
1 berserker set
2 extra rage II
duration=2:51
38 con(no madstone)
30 seconds +6 seconds*con
30 seconds +6 seconds*14

2:51*6 rages = 17:06
Haste and displacement last 2:48 extended. Do song buffs, rage/haste/displacement, enter rage and frenzy. After 3 minutes, heal and rebuff. Build has enough for 18+ minutes of raging between shrines. Madstone before rage/frenzy if you have it.
Feats:
weapon focus slashing, power attack, cleave, toughness, thf, ithf, extend
Can drop toughness for gthf, I have not decided which is better yet. Use min II greataxe.
