Please remove the coins from the bosses.
As already mentioned, you are taking away all the tasks. This is not a mid rate server.Everyone makes old accounts, runs taloc and trades coins to get PvP 50s ACC+ weapon for nothing.
Then you might as well get us the 50 gear. That's no way to motivate people to run dungeons. People look for the path of least resistance.
You can leave the coins in, but they should be more of a nice side gift when you complete the dungeon. So you can also just give it to the end boss that you are required to complete the dungeon. And put this in a good relation to the difficulty of the dungeon.
So Taloc every boss 10 coins is too much. Considering that the box for the PvP jewellery and the weapon only costs 40 coins.
