I started tonight with about 1500 Legionfall reputation required to get Legion Flying and after all the broken shore dailies and scouring the Champion Mission I was on 11,548/12000.
I then went and spent all my supplies on mage tower construction a few times and I was at around 11,950.
So, so close. What else was there to do? I went searching for treasure chests and killing elites, this was slow work and I gave up on 11,966 out of 12,000 and it really was bedtime.
I quickly popped to the refresh my champion missions and they were all either for Legionfall rep or war supplies!!!!!
Well, at least I knowv that when I wake up in the morning I'll have Legion Flying!
