I think you need to learn a little more about budgeting and development process of games. More importantly how budget is distributed to each department. The audio department has nothing to do with the people making maps, spells monsters etc.
Someone in the company is deciding what departments gets what funding. If sound department goes from needing 'X' for what is currenct planned to 'X+cash-for-extra-voice-acting', that means 'cash-for-extra-voice-acting' has to come from the other departments unless they can raise more money. I understand you want voiced lines, I am simply pointing out it not only breaks immersion for me, but will pull money from elsewhere.
