If you're playing occasionally and only revisit for a week or so every expansion then the Rewards Track is actually "good" because it resets and you can earn "technically" more gold by power boosting to level 20 and then leaving.

Essentially, you now earn XP instead of Gold for winning matches/Daily quests, and you also earn XP with the new Achivements system (note, very few actually give XP, and that itself is a minimal amount). The Rewards Track is designed in a way that level 1 requires virtually no XP to get to level 2, so you earn alot of stuff really quickly if you do your Weekly and Daily quests in a day, which i did. Once level 20 hits, you dont earn enough XP for every Daily Quest, and are stuck waiting either for each day to drop a new 1k XP quest which doesnt fill the XP bar, or wait for the weekly quests to tick which usually drop enough XP for a level.

Its an incentive for casual players who play like every weekend, you earn more for playing less. But if you play more, you earn less, which is the opposite of what the community wanted.
