This is literally the rule... You can have FFA sims, it's fine. The ruling was, don't just have everyone running in constantly every 2 seconds. For example, a 30 second respawn timer or 1-life FFA until 1 person wins then restart. Both of those are allowed, but sitting there with a tac at the sim room door, running in and getting killed every 2 seconds is going to cause the guy killing you to skyrocket in level and hence why I made the rule for this.
There's no point in having the Jedi level system and allowing Jedi to have more freedom over their force abilities or utilising WiltOS to its full potential if we throw out the concept of leveling for progression all together when you can just sit in a sim room shooting rockets at 1-hit NPCs or using the 1-hit sniper to farm kills on people. Makes jedi system pointless.
