I think I finished between 5 and 7 arena runs (would have to sign in and check contract to confirm.) I have almost no skin in this game, yet I want to make a couple quick points.
1. The arena rewards as well as the contract rewards for arena were never sufficient to support it. Regardless of how the next mode plays it needs to be eligible for daily contract progress, daily crowns/journey crowns, and have contracts that pay at least as well as standard mode contracts.
2. Luck was too much of a factor. The number of Legendary and epics needs to be set within a range. It should never be the case that an opponent has more than 3 extra gold cards and more than 2 extra legendary cards.
3. The biggest danger with any mode is that it becomes too popular. Seasonal and Arena were never meant to take away from ranked. They were meant to offer a diversion for people who wanted to spice things up and play lower risk Gwent. That said, if they hamstring draft mode in order to keep from getting to competitive with ranked, they will pay a price. The player base who loved arena will be looking for an excuse to leave, and a new mode that takes months that makes the same mistakes and doesn’t address their primary concerns is a lose lose for CDPR and Gwent.
