This is an obvious step in the right direction. Just like the option to turn off animations for the battle victory screen. The animation adds nothing to the gameplay and only serves to waste players' time. It might be visually attractive the first few times; after x amount of times, who really cares about the animation (just like the battle animation)?
This is a good suggestion as it is consistent with other changes inno has made in the past.
Also, could help to bring the speed of negotiation closer to in line with fighting for players that prefer not to fight for whatever reason. I can't imagine many players that negotiate on a regular basis leaving animation on if they have the option to turn it off. Race or no race, no need to waste everyone's time.
Agent - The majority of people here disagree with your opinion as a player and don't really care what you, as a player, have to say about anything. Your speculations (as a player) about what other players do or don't like (or do/don't want) are consistently not in line with the majority of players. As a player contributing to the forums, have you considered letting other people discuss ideas without derailing the conversation with "you can't possibly know that" nonsense? You could at least go the route of "why do you think that?" it's much better for discussion ;-) <3
