yea, my point of view is - when i go play, i am ready to play, ready to finish the match. If someone has ping problems, people around will be waiting and they will be angry. Better not to start the match.
And if somebody has emergency, true, thats bad, but again, someone will suffer from his leaving.
Thats why like nice compromise it would be to do it only at servers i can get tc - tourneys, etc. Or, when somebody is loosing at points and quits, (like elzar in futurama says -) "BAM!" and you lost the match. with rank.
Now i see other problem, that somebody could miss-use it with some sort of deal to improve his rank.
...hm, i have no BAM for this
I just get 3 RQ in a row, makes me angry
