Seeing the Midnight Marauders get decimated by 5+ Vortigaunts and the Red Guard on day 5 and having their businesses raided to the point of being non-salvageable for the most part was a huge detriment to Civilian Roleplay, and I'm somewhat disgruntled with how things ultimately turned out for Day 6, but otherwise feel the event to be more than adequate quality overall and enjoyable thus far despite my grievances.
The Red Guard, the group with the easily most questionable roleplay quality and intent, raiding the nexus on Day 5 killed most of the event's momentum, as Civil Protection and civilians were being attacked discriminately, and a lot of questionable actions from more malicious individuals occurred that day (particularly from the Red Guard) which was upsetting to the people it affected (i.e. combine supplies being eaten in 30 seconds by a raiding rebel.)
Day 4 & 6 were a 6/10, while Day 5 was more akin to a 3/10, as it effectively killed any momentum and pacing the event had been building to thus far, and reduced the event's remaining time from two weeks to only one. With RP hubs like Purgatory out of the way, beyond the Civil Workers Union, there isn't any place for civilians to collectively gather and roleplay with one another in an interesting, safe environment free from the badgering of more malign characters and the frivolous assaults of Gangs.
Hearing quotes, even if secondhand, like "Take off your suit, i want to try it on. Promise I'll hand it back." doesn't inspire a lot of confidence and trust in the roleplay ability of certain groups like the Red Guards, especially when they have a known penchant for violence and disrupting roleplaying, and it feels to me that the majority of their members are more concerned with scripts than roleplay. It may just be a consequence of quantity over quality in their recruitment policy, something exacerbated by the fall of the other gangs, but I certainly wouldn't want the event to devolve into a generic "Red Guard vs. Combine" type of event. By Day 4, the Red Guard, who throughout the event had a rather minimal impact up until then, felt as though they were becoming increasingly more generic by day, and by Day 5 felt more like a generic rebel group than anything profound or unique, something far from its unique (though unoriginal) premises, a sentiment I and many others share about the group's continued conduct, with even the group's own rules are being neglected by its members, likely as a result of it spiralling into the generic, bland rebel group umbrella after killing the other gangs.
Regardless of my criticism towards the more malign groups and characters of the event, I am excited to see how things will fold out tomorrow, especially with the Scarab, as I have yet to see the Scarab take a more prevalent role during the event, and I am disappointed that NPCs like the Juggernaut haven't been used in favour of more recognizable, but equally out-of-place L4D2 zombies.
