Well if a pc repair store cant figure out whats wrong theyre going to go out of business. Its not the customers job to know what is wrong with his pc.You can tell the PC repair shop that you don't know what's wrong with it, but you can also tell them what it's doing that, you feel, it shouldn't be doing. Simply bringing it in and going "it has a problem, fix it now" is going to get you asked to be more specific. If you can't tell them what's wrong with it, or what it's doing and shouldn't necessarily be doing, then they can't do their job of fixing it very well.
Problem is it would take a portion of nexons cash to upgrade servers aka they wont.
iv seen lots of people saying to nexon to fix the lag in the server but nexon doesn't listen.It isn't a matter of them not listening, it's a matter of what do you expect them to do? Everyone is saying "fix the lag". How? How do they "fix the lag"?
