On the take up from standing start point I'm mystified.
I've racked up 11000 miles since June on a 2012 DSG and never really felt it lacking and I live in the ill road mannered, selfish south where a gap of more than a fag paper is weakness.
You need half an ounce of anticipation (no more than to release the clutch on a manual) and give the throttle a measured prod. Oh and make sure if you've been creeping forward it's not slipped into crawling in 2nd.
I'd say the one thing its weak with is cross camber/uphill reversing and even then only when you're trying to sneak back those last 2cm (trying to get boot tight to wall/short spaces). I think it's a product of how the clutch engages so gently at a crawl. If you have delicate left foot skills i still think a manual does this so much better (although I'm getting better with the dsg the more I do it). But it's a mild inconvenience I'm happy to live with.
I tend to:
D - virtually everything (99%)
S - short slip roads
Paddles - if I briefly want to be two gears lower in anticipation of an upcoming gap in moderate traffic (e.G. Middle lane of motorway doing 50, outside doing 70) or for an A road overtake.
Manual - some kinds of slow moving traffic.
I could happily live without everything but D mode but the other bits just make isolated situations a touch easier.
