Utsusemi makes a HUGE difference. I remember when I started soloing on Gigas pets at lvl 21. It was quite rough, and I had a hard time. When I hit 24 and could start casting Utsusemi, the difference was like night and day.
Some people have done pets using /RDM, relying on Gravity. But this requires room to kite, which may limit the camps you can use. And you won't get Gravity until you're lvl 42.
Did I mentioned Utsusemi makes a HUGE difference?
