If you want to make this process slightly less painful I recommend putting on Bending Kamehameha, I forgot to change his move during the video I apologize.
Unfortunately you cant bring teammates (Like chrs or smth) on offline EMs, and I don't know if the supersoul stacks. Sorry I cant answer your question.
So I do this but using God Goku instead. Same super soul then having ki blast stat. With the following moves. Bending kamehameha, kioken Kamehameha. Super guard and ultimate charge. Then the ultimates I have 4x Kioken Kamehameha and Warp Kamehameha. Goku and Vegeta raids are easy and give good tp and exp. I Do the Broly raid with higher tp and higher exp. Just use bending Kamehameha following up with Warp.
PvP is awful in my honest thoughts i've been through this and believe it or not 90% of my Fights were against Cheese presets and Level 199 Modders. People just take this Game far to competitive so i stop playing PvP. Maybe even stopping Xenoverse 2 completely next month when i buy Minecraft again
This video is just a little bit of stuff i experience, Modders and Cheesers are light work compared to getting jumped 24/7 WHILE they are modding. Hell the only reason why I get on Xenoverse is because I have something in the background to watch/listen to.
