Minstrel Tank Without Sigil Of Concentration

I'm looking to gear my chrono for raid tanking and was wondering if there is a way to run the minstrel tank build but without the sigil of concentration.

any alternative is less viable.. But i guess all you need is 100% boon duration and sigil of concentration makes it way easier with the added 33% boon duration..

Try mix/matching minstrel gear with runes and stuff with the GW2 builder and see if you can manage 100% without them.

It is possible to reach 100% boon duration without the sigil, but you should run chaos and have proper food. Once the boons stack up chaotic persistence will keep it 100%.http://gw2skills.net/editor/?vhAQRAse8dncfC9phlfCGoBUrhlejqeUb1Z1MAOtM6cEKhQA-jRx/gAgK/eVCCofAS9Hh9HIFQgr0A-eOr...terrible min/max advise...but if you have 300g to burn you can buy 20 mystical agony infusions just to grind out a little more concentration for 92% boon duration, thus you can free up chaos while running full minstrel. Recommended only to those sick of swapping weapon and run chaos above all else :P

Keep in mind a good rotation muscle memory works much better than 100% boon duration. The difference in few % (or even 10-15%) are quite negligible when both chrono in raid run inspirations. I wouldn't worry too much about getting 100% boon duration, just run full minstrel as you requested and do your usual thing.
