Before you'll say "
No suggestions!!!!!!!1111oneoneone", note as we're just trying to make the pack better, and suggestions aren't bold orders you must obey or be banned.

So...
I prefer you to stop adding weapons just for now, or the pack will never be released. Finish them, and eventually add new weapons in later updates.
I know that it's WEAPON pack, but how about adding some vehicles [or rather making them as seperate pack, but intended to work with this pack], because there are not so many vehicles that can be destroyed with single AT-4 shot [not that many military vehicles, to be certain].
This is just a suggestion...I'm just trying to help...
