That and ONLY that is the point for not opening a server.
If you have a life and in this life you have a job then better don't open a server since your job and your life will require time and lineage 2 server will be 1 more factor that will require time.
So my point is that lineage 2 servers now days does not give that much of "reward" for your work to keep opening servers if you have a full time job on the other hand if you don't have a part time job or full time job then go for it learn and try to evolve the lineage 2 simple and organized.
