In general I agree. Would be nice to have. Besides this there are so many other things that could enhance WOHD. Sadly, there is no one out there who cares.
Specific to my situation and the pairing feature: IMO the WOHD community is very (too) small and I usually do not join races w/ players that I do not know or I wasn't beaten up by them before. I tend to benchmark against the better/best players compared to my level. Therefore, this feature could prevent me from racing against the 3L1t3. I enjoy most of the times being pwned
My win/loss ration does reflect this impressively.
