I know this topic gets passed around all the time and I thought I'd point out a possible fix? It's not classi. Though so I understand if it gets shot down.

Include boss coins in their relative zone. I.E Coin of Cazic drops in Plane of fear.

Coins are trade able for selling to other guilds if desired.
Coins have a .5% drop rate off zone trash or whatever GM sets it to.
Coins summon the boss.
