So is Maw and Claw replacing Tooth and Scale, or will both events be kicking off randomly? Personally I think Maw and Claw is a complete waste if Tooth and Scale events will be happening.. After all, the rewards are absolutely horrible for the Maw and Claw.
It's most likely a test run to see how it goes and what the feedback is, but I actually like Maw and Claw better because it's less points for three stars, so it's most likely just for players like me, while tooth and scale is for more hardcore players 😏
Given the 4 hour run time, it is good they made it less points. If it awarded gems for ranking then it may be worth it. However only gold and shards for fairly common dragons doesnt make up for the fact that we would be throwing away points toward tooth and scale events which grant gems and legendary shards. In other words, if the rewards were better, it may be a worthwhile event.
