Lv 21 Katori gives a bit above 3.8% exp boost when used as PvP flagship. I assume it's base 1% and rest is linearly scaled to her level, meaning lv 99 Katori would be giving exactly 15% bonus exp. Not much if you're grinding one ship but for whole fleet - not bad at all. Not to mention she's already being used in branching rules (E5) and has those delicious four slots. Also, her expedition is still a mystery.
