Not accounting for the actual effects you've provided, my first thoughts were the Necromancer's Amulet and the Bloodworm Helm from the single player games.

You can only apply 1 volcanic curse once every 12 seconds per target. Dealing damage with Lava Whip causes a fiery explosion on your target causing fire damage to other nearby enemies around the main target (Max 5), Increases damage done with Lava Whip by 25%. While equipped you gain Major Resolve, Major Brutality and Sorcery but the cost of all of your abilities are increased by 35%. Scales based on your highest offensive stats.

The dk ones cost increase is insane, would be far too much, but still better than the templar one which would be functionally unusable, I mean come on 35% less recovery in exchange for a 3/5 second cast time on a cc skill.
A better templar one would be your jabs deal 15% more damage and have 25% damage resistance bypass built in but cost 15% more to cast and do 75% less damage to secondary targets
