Unfortunately there isn't much SE can do to improve how well some people play. I understand your pain since I went through the same thing for both Titan HM AND EX. Despite these experiences I wouldn't want them to pretty near trivialize fights because I'm having trouble finding 7 other people who can clear them. The best thing you can do short of a static is to watch others during your attempts and make use of your Friend List or a Linkshell to gather people you find capable. The biggest issue I find is getting a group together and having one bad seed. You fire off 2-3 attempts then exit in frustration and instead of being able to just kick the weak link the entire party implodes. Get the good players on your FL or an LS and you can bring them together later and be able to find that last capable person.
