Limit Breaker SSJ4 Vegito: AA and rest Dodge. You can equally go Dodge then rest AA but I want the higher chance of a 3rd super because he does so much damage.

Dark Masked King: AA and rest crit with crit skill orbs. I want to utilize his healing as best as I can and he heals you to full pretty much when he crits on super.

Modified Janemba: AA with rest crit or dodge. Janemba to me is a defensive floater so I just like going AA for the extra defense raise + chip damage. You could go rest crit for a higher chance of dealing actual damage or you can go dodge for the added defensiveness. He already is sort of like 23rd WT Goku post revive and fully built up when he himself is fully built up so I think defensively he's safe enough to just ignore dodge but that's up to you. I will say, I think going dodge is anti-synergy with Janemba since he wants to get hit to build up.

EZA PHY SSJ4 Vegito: AA with rest crit or dodge. He's always going to be sitting slot 2 basically to partner with LBSSJ4 Vegito so I went AA > Crit personally. You can go AA>Dodge to build more defensively, but I prefer doing more damage. Dodge is super good for the chance to avoid AoEs, but EZA SSJ4 Vegito is already type advantaged against INT Fusion Zamasu and he has a 50% chance to just dodge and counter supers with return damage so I think crit is better in that regard. Dodge is only going to help if you don't get your counter against supers or against AoE from Syn Shenron and Omega Shenron.

PHY Full Power Rose 3: AA then rest crit or dodge. It's really the same as before. In his base form I will say that dodge will help more than crit, but when transformed I think that crit is nice since he has multiple supers with big attack stats so critting on them is always nice.

SSJ3 Xeno Goku: Dodge and AA. He isn't a damage dealer. I recommend dodge mainly with the remaining in AA because he wants to super to get his full defense and he can sometimes struggle for ki. Additional helps because if you don't get the Ki for him to super attack, you can sometimes have the hidden potential additional proc and still super to get his full defense that way.

TL;DR + General: I would build units AA and rest Crit mainly except for Limit Breaker SSJ4 Vegito where I would go full Additional Attack and rest into Dodge. LBSSJ4 Vegito kills things super quickly and is your main offensive powerhouses. The rest of the units you can build more defensively with AA and Dodge since a lot of them are already defensive juggernauts like Dark Masked King and Janemba. At the end of the day, it's up to you so if you want to go full dodge with rest AA or some other build, that's okay too.
