Request to return soldier crit on aiming at boss

[pokemonpasta]

This was a pretty major nerf to soldier that kinda came out of nowhere, and I still have no idea the reason for it. Soldier feels pretty weak now in my opinion, especially with how long it takes to charge a banner. If going back on this isn't a option, perhaps some other buff to soldier since it just feels like a wet sponge now. Some of the suggestions I thought of (to be clear I'm only suggesting any one of these):

• Give the crit on aim to one rocket launcher in particular, perhaps the Liberty Launcher as its reduced damage makes it even less desirable now
• Minicrit on aim
• Reduce the amount of damage required to charge a banner
• Since banners aren't spammed as much anymore, perhaps buffing them, for example by returning backup to 5 zombie scouts
