Switching jobs while in a duty

[SamRF]

This is one of those things where, in a world where no one trolls, it would be a great feature. However, I do not trust people not to troll others. I'm guessing the devs don't either. For everyone's sake I feel that this feature should not be implemented. Considered? Maybe. But the pros and cons need to be weighed, along with an assessment of how people treat others on the internet, and it doesn't take a rocket scientist to figure that part out.

Realistically though, what would trolls do with this? You can already "troll" the party to greater extend by doing negligible dps (just pressing 1 button for example), not performing your role or running into AoE. You barely see anyone engaging in these practices so why would they suddenly be inclined to troll by switching jobs and impairing the party that way?

I think the potential problems are being overestimated, especially considering we already constantly have to rely on other players to be at least cooperative for progression in group content. Doesn't make sens imo that players would suddenly become less cooperative due to this feature.
