You joined the WL, to get into NSC I presume? However you don't play in WLSC because there are NSC nations there. I must say I don't really understand the logic at stake here.
I can understand why it might be seen as strange, but it's a huge help when it comes to building relationships with main roster nations. With the current length (in terms of time) of the WL, I will even say that it is vital, otherwise we would have spent (and the current WLers would spend) years without main roster nations getting to know them. Kinda sad if you ask me.
If one day the majority of the WL wants to get rid of us in WLSC so be it, it should be their contest first and foremost, but the general feeling right now seems to be positive, to my utmost joy. I joined a few months before half of the current WL, and since then we had a lot of fun times playing together and with main roster nations. Now that I am in NSC I don't want to lose these relationships.
I didn't intend to join every edition of the WLSC after I joined, but so far I haven't missed any. This contest is simply too good to resist, and I only regret not joining earlier. I did think my entries would be better received in WLSC than they have been lately, but just like NSC, I'm not in this to win, I'm here to have fun. And I think we all are.
