People abusing party in progress option

[Amyas]

It's comparable to a single primal fight. Garuda takes ~7-12 min to kill (depending on grp) and you get 10 tomes as a reward.

Kill final boss in WP get rewarded 6 tomes. (20%)

Kill final boss in AK get rewarded 8 tomes. (20%)

similar effort <-> similar rewards.

Well, I que in progress all the time and never leave or 'fish' for a almost finished dungeon, but if this kind of thing was implemented I wouldn't q in progress at all, so that's shooting yourself in the foot there.
