Hey folks, I've been wanting to start a discussion pertaining to weapons and how we can fix them, but after reviewing Salamancer's thread on The Weapon Balance Megathread, I decided to revive the thread anew (since both OP's are not active) in terms of why weapons are bad or unfair, and what problems arise.
We're in purgatory until Valve's matchmaking comes out to help deal with weapon balances, and some weapons still have a lot of problems I feel. I think we should discuss the problems these weapons bring, whether technical, tactical, or otherwise, rather than discuss how they should be changed (but these suggestions are fine I think, as long as the main issues pertaining to a weapon are raised).
Please refer to the weapon-making questions listed in these blog posts from Robin Walker when considering your post and the balances/suggestions you make.
