Castle Buff!

As most of you might know,castle got a slight buff recently as in GLAZ can no longer 3 shot his barricades and that is quite major as GLAZ has a limited number of bullets.However his barricades are still quite weak as in they can be hit 12 times,destroyed by grenades and ASH's breaching rounds not to mention the normal charges.They can also be FUZE'd through with no way of stopping it.This makes CASTLE fairly redundant.What i have in mind is that castle should have metallic barricades,only breachable by thermite and hibana,more like a reinforcement but for doors and windows.Also to keep it neutral,he should have only 2 of those instead of the 3 he has now. What are your thoughts?
