"At the right fight"....tracking most guys can't land that many kills but everyone can look at the map and see a vulch.
When I returned to the game for a month , I have not encountered one classic , sustained 'vulch' at all. Which is no surprise at all, given today's numbers.
But when they were, the average k/h were still so low that the potentially resulting perks pale to the amount that can be made by resupplying and bombing.
Even if one managed to sustain gain 2 perks per kill and 5 kills per hour (again, the average is significantly lower) that would be 'only' 10 perks per hour.
And again, with resupplying and bombing you can get 20 easily, no fighting skill and more importantly, no adversary nor opportunity necessary.
One aspects of discussion like these on the forum is that it's often way above-average guys (who often don't realize they actually are) basing their arguments on some anecdotal memories ("hey, yesterday I gots me 30 perks for a vulch! Gettin' fighter perks is soo %&%$% easy!"
Meanwhile, the average guy racks up maybe something like 3-6 perks per hour, sustained. Compared to that, supplying and bombing would be
extremely favorable under current conditions if there was a single perk pool without adjustments.
