What If every downside got reversed into an upside?

example:
No random crit weapons instead have the chances of gaining a random crit be doubled (it was either that or always crit)
The Frontier Justice giving you guaranteed crits when either the sentry dies or the engineer himself dies (and will preserve them to the next death)
weapons that cost metal now give metal, like Rescue Ranger, Widowmaker and Short Circuit
if your wondering if a weapon's downside can't be reversed, it just gets removed
and this includes hidden downside, example of a hidden downside is Demoman losing stored heads on death with headfarming weapons
