I don’t think so. It is a fact that Epic Games needs to fix too many bugs that continously appear on UE4 releases but they even stop the subversion hotfixes now and you are forced to upgrade to the next version which then gets either all new bugs or old bugs reappearing or both.
I really hope that the paid monthly Unreal Engine Studio won’t be the same at all. I would pay monthly for getting more features too but I really hope that at least that version will be far more reliable with less bugs and any bug quickly solved for paying customers. Although UE4 is not really free anyway for commercial use because anyone publishing a commercial game or app made with it has to pay the royalty fees to Epic Games. But still I hope Unreal Engine Studio is going to really be a premium version worth paying for to avoid too many bugs and issues.
