We've heard this all before.
There are a group of gamers who want everything Now, Now Now!
They want to be instantly Level 150.
They want to be able to solo Raid bosses.
They want to have everything handed to them on a silver plater.
I'm not saying this is what you are asking for.
That's just how many of us see it.
This does not make for an interesting game.
The DEVs have done their best to make the leveling experience as similar to how Westwood intended.
Is it perfect? No. But that's ok. It keeps the game interesting.
There are already far too many "easy" ways to L150. An Example mentioned was Trade XP.
I do think a small problem is lack of direction for Quests, as you level up.
I for one am just as guilty at not working on these issues when I could.
There are a ton of fun and exciting quests for all levels.
Finding them can be difficult.
If anything, that should be the thing the Team works on.
Starting at level 1, ideally, you should be given direction to sectors, and missions available around your level.
Making this happen requires a tremendous amount of work; basically revamping every mission.
Seeing as it's a Volunteer Project, it will require a large amount of Content Developers to make this happen.
The best thing you can do, is send Kyp a PM, offering your help.
Also, making broad, general statements about the leveling system doesn't help the Team.
Offer smaller, concise, specific suggestions. I promise you they will spend the time to concider them.
Just remember: The DEVs all have jobs, families, and lives that come first.
