Yeah that battle seems tough, but if you can beat most SBRs you'd prolly be fine.
Also he doesn't seem very difficult at the start, so I guess the trick is to stack DEF as high as you can in the early rounds.
LR gohan and goten are really something though; I'd go as far as to say they are prolly the overall best LR on global right now.
Sure they don't have the busted damage output of LR SV, but it'll take a bit before you'd actually be able to use him.
I think I'm not going to summon that much during 4th anniversary, LR caulifla and Kale are my next target.
