Just a thought about how we as players could incite change
I have been hesitant to suggest this because honestly plarium censors bad reviews as much as they think they can get away with. At the same time they have been shown to pause reviews if a large number of bad ones come in within a short time frame. But complaining and getting angry here only makes things change slowly if at all. And they can't pause reviews forever and they can't get away with mass deleting reviews that don't violate app store and play store guidelines.
I'm not saying don't voice your complaints here. But write your complaints here for players to discuss rather than to attack the team or anyone. Save it for your reviews. If you want things to change give mech arena a bad review on the platform you downloaded it from. If reviews are paused, wait until they aren't anymore. If your review doesn't violate app store/ play store rules respectivel but still gets deleted after the two day review and publishing period, let everyone know.
