1. I liked the RS, just dislikes the fact that people using it as an argument as if Sanji were too weak without it. Love the design, colors, and its abilities.
2. Hope it doesn't return, it would make Sanji's character development against Queen pointless otherwise.
3. The lineage factor boost is 50/50 for me. I don't like it nor dislike it, but it gives more benefits to Sanji than the RS would.
4. Fuck evil Sanji.
5. I guess that in the future where Sanji meets Vegapunk, he would explains the concepts of linage factor.
