Force in Silkroad
Alright look, you still do not get it. Both builds can not debuff cleric, but glavie light/cold still has the more defense, and the glavie/force is Silk road gold stuck with less defense and a useless skill tree in game(SRO Gold). Also it does matter on your set, but not everyone is going to have a set like you said you had. Now if you both had +7 set and 100+5 legs/chest/necklace good blues/whites and so on.
Glavie light/cold would still have the more defense and Glavie/force is still stuck with a skill tree in Silkroad, he can not use and less defense. So in the end, we would rather have the more defense, have a better chance at surviving than having less defense and a skill tree we can not use.
