Nope, sorry, sitting on the Harec is for the good of the mission. Also It forces the baby Harec out of his comfort zone and he is forced to play another character. Another character that would beneficial for him. Plus, they make you recruit Hans almost immediately.
If your skill with the game is such that one person picking Harec over another literally is the difference between success and failure then you are not skilled enough to be making judgement calls on other people's ability to play the game.

You didn't ever get off Harec so we don't know if that person was going to pick them or not.
Also, the person picking Shae almost didn't because they thought you were going to pick Harec which more proves my point about the inherent problems with such a method. The person picking Shae was only level 17 and yet that doesn't seem to concern you at all.
Which leads me to believe most people who complain about "baby Harecs" are doing so because it is a popular thing. Jumping the band wagon, as it were. Level 2 Harec and Level 17 Shae should, by your own estimation, be equally useless.
No one has yet to identify the exact thing that is wrong with allowing someone to pick their character they like.
Perhaps the solution is as simple as there being more people who cannot complete a mission with a low level handicap than people who can complete a mission with a low level handicap. Which makes sense, not everyone is going to be good enough to do that as this thread shows.
