I've wiped twice and at the time I was rank 13 and 7 respectively for soldier. Obviously I wiped a lot of runs and a couple of wrs (not over the 5 limit) but if I hadn't have done that I probably would have completely quit. Wiping completely refreshes my want to play this game and that is the sole reason I do it, not to just be annoying and 'oh I wiped yeah give me attention'. As for soliders being able to complete more maps, I don't see the problem in any way.
