you earn your vet 5.
i think all vet 5s should be very hard to reach not just 25 min mark reward (for volks) just like how vet 3 is basically a 10-15min mark reward.
I agree, but the vet 5 requirements as they stand right now are absurdly hard to reach. I'm not giving a figure, I'm saying that the current figure is too high.
Edit after reading your second comment:
a) Those would be the two extremes! What's to say there isn't a plausible solution between those two options.
b) This is a model that could work, sure, but what does that have to do with ease of reach? Even a vet 3 commandopanther is a rare sight. With the current vet bonuses, it HAS to be rare otherwise it would be game-breaking.
