I've been thinking if i should cap my rogue or not.

I wanna know if 41s are best at running arena/elite tind/planar tombs since arc ring benefits them the most compared to 46s. In addition, if a 41also has imbued sets + planar pend + Mythic Elo arent they gonna rock harder in the zones ive said compaired to 46?

I need answers that will prove im wrong.
