MCH is a good but

[myahele]

In all honesty, I think MCH has it worse. If AST's RNG was like MCH's, their heals would have completely random and unreliable potency.

Edit:

But... ammunition does give you guaranteed procs.

Sorry, but it doesn't. It just increases the rate, but by how much, who knows?

Reload - Loads firearm with five rounds of special ammunition. One round of ammunition is used each time a weaponskill is executed. Increase that weaponskill's potency by 20. Ammunition use may also increase the rate at which a weaponskill's additional effect is triggered. No more than five rounds can be loaded one at a time. Duration: 30s. Recast Time: 60s
