Safer thing is not do anything at all.Regardless to how easy you believe it to be, this weekend we shall only be reducing the windows to one third.It takes more than one member of the staff to change the spawn timer of bosses? I really find that hard to believe.
Someone already went thru them all and changed their spawn windows and reduced it by 2/3. All they gotta do is go back and change the minimum and maximum spawn time and reduce the range.
It is a simple and safe change that can cause no errors that may harm the game.
We may change it to fixed in future when it is more feasible to us but for this weekend it shall just be reduction.
But seriously, you guys change Snorri spawn window from 2 hours to 10m, changed Event bosses from 2 hours to 10m, changed Otherworld boss spawns to 10 mins. It has been done several times, already. Changing the spawn window shoudnt cause any errors at all, it is after all just a parameter change.
The reason why players hate these fast spawns is because it entails all day camping. That was the primary feedback last mini event, and I think OTM shouldve listened rather than ignoring us, YET AGAIN.
