SE has decided that they want each person to have a shot at 8 HA, 1 T9 weapon, 1 UAT, 2 oils, 2 sands a week (Assuming perfect drops and your the only one looting) and I personally think that is fine since it is across the board.

So under the current system a static would get a max of 14 pieces of gear a week. With your system a static could get 126 (14*9) pieces of gear a week. This wouldn't help any other people since it would just be the static gearing alts since they have every job at 50. Given that there are only 13 slots per char you just made it so they would only be running coil for a few weeks. And then never logging in according to your logic.

Assuming you have every turn on farm status with each combo of jobs. Your talking about ~1 hour a week (lockout per char) to ~9 hrs a week (per job). So assuming 3 hours a night of play time which is very little your system would get people from "logging in once a week" to logging in 3 times a week.
