diablo 3 guide for barbarian
Heal is nice during early game but later on becomes useless. 4k heal every 30 seconds cheap Diablo 3 gold? Imagine that in Inferno... no use at all. Intervene is one of the reasons for which you would even consider picking Templar.
155 life regen per second is not that bad I guess... though pick whatever you want here (if you are in need of slow, feel free to take Intimidate).
Same here, pick what you prefer. Though i doubt that you will be able to equip your templar with decent 1h so that Onslaught is actually worth it... and charge got a potential to save you.
This ability will save your life, same as Intervene so take it if you decided to pick templar. Inspire might be nice if you are going for pure dps, fury generation oriented build I guess...
