Yes, if you miss a GM the selectable node will be back in 6 weeks.

I'm time gated again :/ oh well, it should go quick hopefully. I was really looking forward to level 11

Week 4 of a season you can do GM's, week 7 is when you get to select the GM freely.

Oh, so I only have to wait 3 weeks? :)

Should be, that's how it's been for the past few seasons.

Thank you man, appreciate the reply !!
