They need too limit instances to once a week, with higher drop rates. Doing ifrit 100 times with no drops is very disappointing, but doing ifrit 10 times and getting a drop, is a lot better. That took 10 weeks to get the drop you wanted(or sooner) that adds life the the game. You can also make better statics with that as well, with your ls and friends. Same goes with the dark-hold instance. People got all the stuff in matter of one day for some people. That doesn't add depth to the game, it shortens the life of it.
