Plex0n, I still consider you to be the leader, even though you are busy irl. You've been able to make hard (but good) decisions, you've been responsive to member's needs, and you've been open and diplomatic about faction matters. I see no need for a leadership change, as things seem to be going pretty well now.
As for a second-in-command, I think that there are many good candidates. Kanichan obviously springs to mind--he has done a lot for the faction, and has a lot of good ideas. Screwball has also been incredibly steady and supportive throughout the entire time that I've been a member. N1njaStr1ker is obviously an all-star, but I doubt he would want leadership because he is also busy irl.
Then there's Nossualc, who is usually quiet but his numbers belie a great contribution to the faction. And Bensonk is always there--dependable in almost every war for a positive contribution.
Personally, I don't want leadership because I've led a guild before and I know it's a pain in the ass. I spent more hours worrying about how to handle guild drama than playing my characters. On top of that, I tend to get into a lot of leadership positions irl that tend to take up time and brain cycles. I'd rather just play for fun, contribute a little extra, and carry on with my very busy life outside of this game
There are many other great candidates in the faction, but I think the greatest evidence that you're a good leader is that you are willing to even consider a leadership change for the betterment of the faction. Your busy season will pass, everything will smooth out, and things will go on as they were.
