Galvanized Scope & Crosshairs Rant
I tried to love them, but for their cost compared to the basic versions, they are simply not worth it. Putting aside the bug whereby the stacks decay all at once instead of 1 stack at a time, I try to be as objective as possible.
The base +crit chance on headshot should be the same as the base version due to the huge disparity in drain. The 12 second for the 'on headshot' condition is fine.
On headshot kill, fine. I don't mind direct dmg kills. But a measly +40%? I'll take at least 50% at least if I keep focusing on the heads of enemies.
The worst offender: ON headshot kills, stacks last for 12 SECONDS. Who balanced this? The other galvanized mods offer 20 seconds on kills, this one takes more effort to get 12 seconds per stack.
On headshot kills, +40% crit chance per stack to max of 5 --> 50% crit chance per stack to max of 4 (I wouldn't mind if you increased it to max of 6 either)
Stack duration from 12 seconds to 20 second minimum
And please, fix the decay bug.
