Bump

Typically you'll want wrecking blow, executioner, and rally no matter what class you go with. There's 3 of your 5 slots. Fill the other two with class abilities as you please. I'd use critical rush in one slot, unless your class has a better gap closer (like chains or ambush). Usually an extra healing spell in the fifth slot is preferred, as between a magicka based heal and rally you can get some pretty hefty survivability using a 2hander. My nightblade swaps between shadowy disguise and strife/swallow soul for that slot. For a templar, I'd go with either a basic heal spell or possibly eclipse or backlash. Eclipse for dealing with caster enemies, backlash for extra damage potential - backlash with wrecking blow spam is pretty potent from what I hear.

If you've got access to it, flawless dawnbreaker is a great ultimate to pair with a 2h bar, boosting the weapon damage on that bar by a hefty amount. The harder you can make your wrecking blows hit, the better.
