Blockland Glass is a really good service and I don't know why anybody would refuse to use it other than being stubborn for the sake of being stubborn.
This weapon pack is good and I wish it was used more, yes, but I can see why it isn't. The selection it has is lackluster and could be more.. themed? The guns are sorta just all around. Even still, 'skin' packs would be really nice to see, similar to how tier tactical did it. Those could be themed.
Things the pack doesn't have that most servers could use are things like an actual assault rifle, or smgs like the mp5.
