Are you looking for just one person to make it all? because alot of people have different strategies and ideas. I'm positive mine is different than most other people who have solo'd but maybe thats just because things were alot different back when I started.
I've solo'd all 3 HQs multiple times so I know my stuff pretty well. I've already got a guide I made for some friends that I can work with but it probably needs some adjustments made by now. Just let me know if you want the help.
