Well that told me didn't it!
A couple of points, even though every member has broadband it doesn't mean we don't still get connection problems, warp is the single most annoying,race spoiling aspect of online racing so anything that makes warp less likely such as making sure vertex damage is off is a good idea in my book.
In some respects vertex damage adds realism but in others it removes it, drivers heads poking through roofs, arms through doors etc. and general unrealistic looking damage.
Also, vertex damage makes no difference to suspension damage.
Uk-dirt does pay attention to this forum but maybe they don't necassarily pay much attention to newbies telling them how to run the league, they've been doing it long enough to know what they are doing!
