This isn't something that would be good for ranked pvp. If you have many people knowing they can get ez tomes in 6 mins or less, there will be people getting into matches with more experienced people and making it frustrating because they haven't researched their role and responsibilities. In frontlines when the tome event comes around there's a problem with people making noticable mistakes, not caring about winning or or losing and sometimes straight up throwing. With feast the problem would be much worse. The only potential upside would be giving people more of an excuse to actually play the mode and find out if they like it or not, but that wouldn't really be an ideal scenario for them to experience it, or maybe it would be given that there would be less 'vets' screwing up low tier match making.
