I started farming recently myself, Rad/Fire Brute and I was amazed at how easy it was to get started. Now, I just hit 50 today, so I am still new, but what I learned was that I could farm +3 * 8 with just SOs. I was amazed to be honest, but it makes sense. Once you get going, the inspirations drop like candy, so I just kept eating Luck and Good Luck and kept converting them. So my Fire Defense is about 5 or 6 to start but I get it over 50 almost all the time. That is what I focused on, managing inspirations. Use the double xp from P2W vendor and I went for 33-50 solo in 4-5 hours.
I used other toons for standard play of course.
