Well, the 'Tabletop RPG' event in Duel Links is fairly entertaining, if a bit slow if you don't pay for the stamina upgrades. Still, it's a good change of pace from the repeat events and we get this thing as on a playmat, so at least its ascetics are put to good use (and it fits the Bakura RPG theme).
However, the lottery rebalence is horrible. Sure, they are giving up to 10 gems from a draw again, but that won't matter with how slow the event coins are gathered. You'll be lucky if you get 3 copies of each event UR/SR card this time around.
