This!
Well, after competing in it for 10 years, maybe this year is time for LD to 'experience' the WC from different point of view. This time he can let go all those pressure he had experienced before, just relax, sit back on his couch back home, have a cup of coffee, and watch how his teammates and rivals deal with the pressure of the tournament. Who knows, the excitement he feels might gave him new motivation to compete again the next year, and maybe win it once more. Afterall, WC 2015 might be his last chance to established that tempting, great record, 6 times world champion!
Yes, you have a point there. But still, he won lesser titles compare to LCW's. How i wish he can win as many titles as LCW had won.

That should be a good reason for him to back in competition, shouldn't it?
