Really? Requiring 50 keni would actually feel kind of nice. I dump so much damn kenki into Senei so often it's like if MNK's brotherhood effect lasted for an extra 10-15 seconds. It's ridiculous and just boring popping it. The only thoughts I have with kenki is with a specific party comp. If we have an astro then sure I'm storing kenki till I get a card but otherwise it's just kind of "dump as you get".
