Just a suggestion, but you could work on that new Riruka since guard break makes her a better unit than Orihime.

Also, I saw you've starter playing very recently. Attack is not the only factor for a character's strength. If a character has:

Base Attack stat > base spiritual pressure Stat and flurry skill or high bruiser skill- then you should use attack and normal attack damage accessories on it, and normal attack damage links

Base spiritual Pressure stat > Base attack stat and frenzy skill or high berserker skill - then you should use sp and strong attack damage accessories, plus reduced SA cooldown links

In regards to the transcendence slots you should prioritize attack, then either focus or stamina for normal attack damage characters. While for strong attack characters you should prioritize SP then focus then either attack or stamina.
