It's 12% of missing health and you underestimate the value of the added range, which combined with the slow can enable you to stick easier. Stealth provides an extra hit of unseen threat but if the target is missing 1600-2000 health @ lvl 18 (depending on your AP, the latter value at 100 AP, former at 0) evolved Q will deal more raw damage but since it's also physical and your ArP is in effect it won't be mitigated by as much.

In your scenario the tank with 3,000 hp missing and 200 armor, vs. full stacks of cleaver, ArP runes and the 8% mastery should be down to roughly 100 armor, which means evolved Q would add almost 200 damage. That's more than the raw damage from Unseen threat and nothing to dismiss.
