Yes, I agree with OP as there are more high ranking members bullying newbies instead of helping them to improve further. Assisting the newbies is a great way to let them enhance their knowledge and grow maturely.
For your information it's not the higher rank's responsibility in helping newbies to improve, that's why higher rank won't help further. Newbies and the demoted jr. members should be responsible for improving themselves. Higher Ranks just pointing out where to start and it's on you to continue learning. Having trouble? If yes, this forum will be good for your problem discussion about the topic you have problems with.
