Your party/alliance leader cannot press this button while KO'd- thus a group can even unintentionally monopolize a monster without being able to defeat it.
Emphasizing the leader keep RR active and use it responsibly is a bit more sensible than the "suck less" mantra floating around justifying the system's current flaws. Besides, some are also too quick to determine when a group has no chance.

Overall, I can understanding not wanting to waste time or stand around with your finger up your butt at a contested mob. Ideally, the better solution would be to further expand on the amount of copies an NM that can be up to encompass all popped mobs much like they recently did with the zone bosses and such. The goal is both minimize the chances to steal and the temptation to.
