Oh just remembered one. For the Skirmish Stone and Arcane Glyptics Campaign make it work for alluvion skirmish too.

Given the recent update made the gear pretty good for smn again albeit with slightly different augments than most had and given the whole trying to help returning players and this is one of the higher tier of gear a returning player can hope to solo and Skirmish Frenzy Campaign - PLUS! upping the drop will get some people to want to do it but the amount you can effectively farm especially of dusk is low enough combine with the fact you took the stones off of ambuscade that might hard for really anyone to get decent augments
