My friend, always you have to notice 3 things when formating a def team.
1- Special skilles goes from left to right.
2- Don’t put 2 heroes of same color side by side, thats how your opponent will easily targetting them. So put Li Xui in place of Buddy.
3- Put the heroe with higher defense in Center /Tank then the less abit defense in flanks and the weaker in wings.
So depends on your roster or this very team … I think at this point Grimm has more defense than Li Xui … but after maxing Li she will have more defense than Grimm.
But I am not sure if Buddy has more defense than Grimm at this point or not.
A screen shot of both will be great.
