The Syndicate is internally discussing this issue now. Once we have a decision, we will announce our stand about this.
I personally believe that since SirEmi designed it that way, it doesn't mean that just because you don't like it we have to change it. I personally like it the way it is. Comparing it to COMs is wrong because COMs don't ask you to invest something in it first. It is more similar to the new mining mission, where you are asked to invest something first, and, like the crash site, you don't need a ship all the time to do it since you already have invested in it.
You are also wrong to think that it only takes 6 hours. Some take a week (maybe even more), some a few days. And the required RPs increase as well.
Since a players name is indicated once an investigation starts, the game even recognizes that that particular crash site belongs to that player. Starting your own greedy investigation on top of an existing one is for me an act of war.
Again, SSS will announce its stand soon.
