Totally agree here.
By the way I don't really see an issue here either making this thread was pretty useless since your just complaining and/or annoyed. I get the point though, but really? Removing the P90 just because of this isn't an issue, people do this all the time to the point where I really don't care anymore and besides you weren't following orders so It is your fault, nothing you can do.
Also there are other guns that can do more then 90 damage in 1 hit as scrolls mentioned before.
