I don't think it's a good idea to disallow the "minor" c-bug. I think it's very important to deal with bugs in a reasonable and clear way. In the old PTP it wasn't always clear what we considered bugs, one admin would consider something a bug, while another admin wouldn't and it only confused the players. People thought certain bugs were allowed and then were suddenly banned for it (for example, switching to reload). So, we decided to, instead of forbidding all bugs, focus on a couple of bugs (2-shooting, c-bug and slide bug) which we thought were the most well known and gave the most advantage. This prevents a lot of questions and a lot of confusion, people don't have to ask admins anymore if a bug is allowed or not.
Another big part of this is that these bugs are easily preventable with scripts. New people don't even have to read the rules on what's allowed or not, if they try to C-bug or 2-shoot, they'll get automatically warned, so they're immediately aware that they can't use that bug. We no longer have to deal with reports about bug abusing, which also saves us a lot of time. I think with the "minor" C-bug, we'll have a lot of 'grey zone' (at what point is it bug abuse?). Some people just might just crouch once, maybe stay crouched and get up again for the last shot, so they'll have fired 2 shots in a shorter time. Or they'll crouch and get up again, to move to another place. Anyway, I think that we'll just end up with a lot more confusion, people that don't know about the rule or what exactly it's about, and just a lot more reports over something that only gives you a little bit of an advantage.
This was just my personal opinion on it. I'll lock the voting Sunday at midnight (GMT+1), and we'll go with the option that was voted for the most.
