Why not allow class changing during duty finder dungeons?

[Naunet]

One example would be;

- Enter Dungeon
- Tank Swaps to WHM
- You're now without a tank

The problems with people abusing it are the only concern ESPECIALLY with a loot system similar to what we have know;

-Finish Boss
-Tank swap to DPS
-Tank rolls on DPS item as they've swapped classes
-DPS miss out on the roll because the tank gets it.

For your first example: This wouldn't happen nearly as much as you think it might, if at all. In both WoW and Rift - MMOs where you can swap your specs mid-dungeon as long as you're not in combat - I've never run into any instance of this kind of griefing, ever. Far more often I've seen it come to good use when a tank or a healer has to drop party and someone switches specs/souls to fill the role instead of having to wait 30+ minutes for someone to queue.

And as for your last example... Just lock the roll to the role you were in when the boss died.

The abuse potential in cross-server trading is too high. Have nothing to do with class change restriction.

Obvious solution, which other MMOs have already established, is to make trading available only to people on your server...
