As we all know in that game is relogging exploit what we talked many times. Robigo, quince, mission stackin, ranking up. Everything is connected to logging in and out to the game in a purpose of unlegit refresh bulletin board.
Normal refresh is 15 minutes, reloggo is less than minute.
That exploit is giving an 10-15 times more advantage than normal play.
Not bashing the OP, and I do see some merit in alternative refresh methods, but surprised 3 pages in no one has pointed out the factual errors to OP's assumptions.
Opinion is no right or wrong, can agree to disagree etc, but plain facts are:
1- No, we all DON'T know that relogging is an exploit.
FD has never stated mode relogging is an exploit, unlike other player actions they have come out and posted clearly is unintended and labelled as exploit (e.g. combat logging after combat initiated)
So while it's perfectly valid to not like it, not do it, and even wish other players didn't do it - saying it is an exploit doesn't make it so, when FD won't label it as such. Since FD is perfectly willing to come out and label other actions as exploits, it seems clear that at least for now, it is by definition not an exploit and condoned (if perhaps not encouraged, it is at minimum a tolerated activity and not labelled by devs as exploit)
2- No - reloading does NOT give "10-15 times more advantage than normal play"
The mere act of reloading to a different mode does not automatically refresh the mission board. Each mode has a separate timer. If you take missions from Open, switch to Solo and grab missions, then switch back to Open - you will not have new missions. It doesn't work on that 10-15x faster scale as OP incorrectly states.
I believe the server refresh is something like 10 min, perhaps 15 but seems like 10. No matter how many times you switch between modes, if you switch faster than the last refresh, you won't get new missions.
It does easily allow you to double up, so at minimum it does allow 2x scaling of mission taking. Perhaps a bit more if you get lucky and the timer was almost done when you grabbed it on one mode. So somewhere between 2-3x, with 3x as max. Nowhere near the order of magnitude larger OP incorrectly states with the 10-15x hyperbole.
3- I entirely agree that relogging as a function to play is not a good experience, even dumb. The rewards due to current poor mission board mechanics however has some players, including me, do it despite the negatives because the positives still outweigh it.
If you don't like it, don't do it. Calling it an exploit when FD clearly has not is simply trying to force your nanny state wish to other players.
