Yeah I saw someone there every time I went, too. Like you say you're gimping yourself if you don't do it, especially now that endurance and strength level at a snail's pace legitimately. It's so stupid, a legit player will have like 10 endurance/3 strength by the time they're level 35-40, so if you don't exploit, then the exploiters have a massive leg up. Especially since it's taking BSG so long to patch it, and all the while they're advertising that it won't get you banned (which also tells people who didn't know about it that it exists). Almost 10k views on that video now....
Only seen one invulnerable hacker so far, but hackers do seem more common this patch judging by all the reddit posts about it.
