All of the non-launcher ranged weapons (bow, xbow, wand, gun) are Fast +1 while launcher is Slow -2. It's understandable that a large weapon would be slower than the others, but 3 tiers slower is a ton. No other weapon comes close. Axe is Slow -1, but it's a melee weapon and melee weapons have faster attack animations. If both weapons stood and attacked for a minute axe would get an extra 10 hits off.

What this means is that launcher normal attacks are significantly slower than other weapons. It also means that they hardly scale with extra attack speed because that value is calculated as a percentage increase of the base and their base is awful. This is quite noticeable in game. I find it painful to weave in regular attacks between my skills on my launcher artisan.
It would be a small buff at most, and everyone knows guns are better than launchers right now. Guns get huge attack speed steroids anyway so launcher wouldn't be stealing their thunder.
