So I absolutely love r2 and chewie and threepio. Their abilities to pass on stat boosts to allies of proper alignment and chewie's additional assists make for quite an onslaught. While my chewie and threepio are only 4 stars my r2 is currently at relic 5 seeing that I use it for my jedi training Rey squad and commander Luke team. Would it be worth the trouble to take both toons to relic 7 for maximum stat boosts for allies or not? It's been a while since I used either squad without r2 so I wouldn't know if there would be a noticable impact on their effectiveness.
