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 stuck with less defense and a useless skill tree in game Silkroad 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 defenses, have a better chance at surviving than having less defense and a skill tree we can not use.
You can not say a certain build is good just because you have a good set like that. Any build is good if you have a good set like that, if you know how to play your build in game Silkroad online gold, but if the build is only good with a set like that then it is not really a good build to us.
