Thanks for the feedback! To quickly go over some of your points;
We absolutely agree with you here.
Last Epoch entered beta less than a week ago, and the optimization is as much of a work in progress as other aspects of the game. You can expect continual improvements here.
We are continually improving animations - we include new ones in almost every patch.
Voice acting is planned, however is usually one of the last things implemented in a game.
The most cost-effective option is to wait until all dialogue is considered final and we are reasonably confident that there will be no large changes to even an individual quest prior to paying a voice actor for a day’s work. Making changes later can be quite expensive.
If you come across bugs please do report them and provide as much information as possible.
While we want skills obtained through class masteries to be iconic and impactful abilities, they are not intended to be objectively more powerful. We want all skills to be on an even footing so that people don’t feel bad about playing their favourite skill, and the game has as many viable builds as possible. We know we aren’t there yet - but we’ll keeping working on it.
I can definitely understand that it may feel bad to be excited about getting access to a mastery class, only for the skills to initially be weaker than what you’re currently using. I don’t have anything concrete to offer at the moment, but I’ll discuss this with the team.
