If you look at the release notes for Patch V1.03 for Vegas 2 under High Stakes It says:
"- Auto-aim is completely disabled"
Since High Stakes mode didn't work for more than one round on the PC version of the patch, and was NEVER fixed, I never bothered with Vegas 2. Thanks for nothing UBI.
In regards to Camping, there are plenty of games out there that are Run N Gun with unrealistic methods to keep people from camping and allow respawns, so I am sure you can enjoy those.
Camping is a legitimate strategy in any type of situation with an objective that must be captured/destroyed for the defending team. Part of the fun for offence is finding a realistic way to defeat or circumvent the campers defending the objective. Cover fire, smoke, flashbangs and other strategies that Run N Gunners hate are some of the ways to accomplish this.
Respawning, Seeing magically over walls without being seen, having icons allow you to cheat by telling you something you wouldn't have otherwise known, and health regenerating in mid battle are unrealistic and contribute to this Run N Gun playstyle that Rainbow Six was never about in the first 3 versions of the series.
