People need to realise that the voice lines are not bad quality. They're not affected by poor quality recording or mic. They have edited the voice lines to convey what they would sound like underneath masks or helmets. If anything they're going for accuracy. The voice would be slightly obscured if you wore such armour or helmets. People need to stop complaining and actually listen and realise where the voice is coming from.
The only thing I agree with though is the wardens new voice. It was a bad choice to change. Of course the original voice actor is a very popular voice actor for video games and anime, so it would be difficult to get him back considering he might have a busy schedule or other projects to work on. If anything, get someone who sounds just as gritty.
The last thing I don't agree with is the highlander's new voice. I like the direction they have gone, having Scottish heritage myself I love the direction they have gone with him. But certain movesets and attacks now have an even more cringy and spammy sound than before.
To conclude, is it just me that realises that certain heroes wear masks and helmets and voices need to be changed accordingly? Only ten percent of the player base seem to think so. Maybe its just us paying attention to whats on their face.
