I'd suggest this if you wanna get the title fast, but not kill yourself trying:
Note: You'll have to contribute at least 3 hours a day, if not more.
This is what I recommend doing. However, if you have to miss a day, then you're pulling back everyone unless they ditch you.
I'm not sure if you have to do the 6-10 stages 200 times for rigel then soldin, but if you do, then just here's the other schedule:
If you change your schedule, and do it during the summer, I might join in.
Btw, try to get your levels in this range:
History stages to Legend 4: Level 71+
Legend EP 5: Level 76+
Legend EP 6: Level 80+
It'll help clear stages faster.
@tommmmmm: 2-10H should take less than 2 minutes. I do it in around 2 minute 30 seconds solo, so a team of level 70s will clear it in less than 1 minute 30 seconds if everyone knows what to do.
