The new update is supposed to be about 7 times more rugged as far as resistance to clutch failure. More cooling as mentioned above but also much more lubrication. It’s been a lot better. Was disappointed in Honda quality myself on this one but they did slowly take care of things and is now more the machine it should’ve been on day 1.
Any transmission setup can fail. If asked to do what a lot what some of us do a belt would likely fail much much sooner. Yami belt is better but Polaris and the others are very failure prone.
Changing clutches isn’t to big a deal and someone can change them for around 300 here’s the guide if you’d like to look

Any rig has got to have slip somewhere. Belts included. The dct has much improved since it debuted and imo is so much better then the belt. We also have a Yamaha and I do like that particular belt (wouldn’t own any others anymore!) but it’s just not the same. The positives far exceed the negatives including longevity!
