Just your average Law-Student, who found the Path of Webnovels =D .
It appears that I was not the only one to think exactly that. =D Not sure if I would say that the quality has dropped per se, but unlike in the beginning now we're getting backstory to backstory to backstory... and I get that it's all important, and admittedly also interesting, but the way it's presented it is hard to keep track. It doesn't help that there isn't really much of a headsup when we're getting into the next arc/backstory, especially since the MC has split into different personalities, and you can't be sure if we are following CC, or some of his Alter Egos. I am in the midst of the whole System Origin Backstory, so hoping it gets better in the next 100 chapters or so ^^
Unfortunately, Blake isn't in the meeting, else he could give us insight. My personal guess is that they might have records about vampires, but perhaps be clueless about their current existence, similar to how it seems to be with the Werewolves.
It's true that Gary was an Omega who turned Billy, although that alone didn't result in him being a Pack member. However, there might be a difference between a banished Omega and a non-banished one. We don't know enough about Werewolves to be sure yet.
I assume you refer to this part: [Grey Werewolves are a rare breed who gain extra strength whilst in the company of their kin, even if they’re not part of their Pack. Due to this, Grey Werewolves are often feared by their own kind, as they tend to come out on top when fighting their own.] Assuming extra strength is kinda like an overall buff (unless JKS intends to just limit it to Strength) this should answer your question. Alternatively, if we were to put it into numbers, picture Kai as a Lvl 20 Werewolf, even with a 10% bonus, he doesn't really have to stand a chance against a Lvl 35 Midwak. (don't quote me on the numbers, just used them to illustrate my point ;) )
As we discussed on discord, most, if not all, of Gary's decisions to invest his points, choose his class/skills, have been more spur of the moment things, rather than thinking long term. In this case, night time bonus was something that could help him right now. Besides, as he himself mentioned, we don't know how rigorous the "righteous" requirement would have been.
Numba is only aware that Gary is backed by a gang, and that it is a Tier-3 one, but not that is the Howlers' leader. Even if he knew, I don't recall his father having told Numba about potentially teaming up with the Howlers, so we will have to wait until they meet (maybe on the battle field :3 )
