For the incoming event, is it possible to give a special fixed common drop to Olga flow as a reward ?
Such as a special weapons badge that you get instead of mesetas or consumable on the boss, and at the end of event people could redeem it for some rewards. Doesnt necessarily needs to be something great, could be like "10 RT badges for 15% attribute on the weapon of your choice"
That way, not only people who claim they did over 500 runs of RT could actually prove it but also that makes a consolation prize to people who farmed seriously the PGF without getting it.
