Are there quests where you gain skills in nightfall?

Im going to get nightfall soon and i was wondering if there were many quests were you can gain skills for your characters? not just the beggining skills like factions but getting all sorts of skills like in the first campain. Thank you.

its like factions only at the start

However when you gain ranks in the Sunspear and Lightbringer tiers you are rewarded with 'Hero Points' which you can redeem at a 'Hero Skills' Vendor for the cost of 0 gold and 1 Hero Point. These skills are both then available to you (as if you had purchased it from a skill vendor) and unlocked for PvP (and hench useable by your heros) you can unlock skills for any profession not just your primary/secondary at these Hero Skill vendors.
