The problem is R2 gives out his: health, protection, potency, and offense. With his relic only boosting the first and last. That being said he's still my first light side relic solely for that as it's another ~17K and 2K offense before mods are taken into account. Granting insane damage to GR, even more to CLS, and a flat health boost across the board which help especially GR's protection up. So TL;DR yes
