Chain damage is mitigated in a few ways. Only have a few people run at the start, so that when chains come out fewer people are far apart, reducing the chance of bad chains. Once chains are out, get them to ~13 during jasper if you can, but don't break unless you need to. Run during Powering Down w/ the person you are chained with. Annoying, yes. But once you get the hang of it, easy.
And we have 2 melee as 10m, and no problems.
