For people who are bothered by the extra attention being paid to the competition team - perhaps you're missing something about the lifecycle of jiu jitsu instruction, and something that I think is quite wonderful in the Jiu Jitsu world (in contrast to many other sports).
With respect to the "lifecycle of jiu jitsu instruction". Generally speaking the first part of the instruction is directed at everyone. You get shown the technique a number of times from different angles and the major details are pointed out, you're then partnered up to practice the technique.
Most instructors I've seen (even the ones who appear to favor the competition team) go around and correct most people or are at least available for questions if you have any. During this period they *might* spend a bit more time on someone on the competition team, but for the most part - the extra attention the competition team member gets is during rolling periods or competition team training where their sparring gets a closer eye and more analysis than the average student. Part of this is because they want to make sure their team does well, and part ofthis is because there is probably a greater return on "investment" so to speak.
But the benefits to that scenario don't stop at the person who is competing. They're also our training and sparring partners, and when the coach is busy they're often able to help us out (when they're not pushing us by being a more formidable roll). I can't think of a good analogy for it yet but this seems to be a pretty good way at ensuring everyone gets the most out of training.
If you're talking about a situation though where the instructors essentially ignore people who aren't on the competition team then that's different (luckily I've never seen that)
Regarding my last point -- I just think it's absolutely amazing that I get to train with people who compete internationally on a regular basis. High level competitors still working and training with the average club member is something that isn't seen in every sport - the higher up the competitive ladder they get the more isolated (and inaccessible) they become. But in your first six months of training you might find yourself opposite a local killer who will of course take it easy on you, but it will be an educational moment where you have a level of access I don't see often in other sports.
