Celtic Heroes

Title says it, i have recently bought a good amount of sigils and was wondering whether or not someone has found a way to use them in combat(the usual running around trick)
Also please post about methods used recently since the previous patch ruined the old ones
Thanks

Freeze

No auto. Seems trivial, but I have seen so many druids and mages autoing, and it just keeps them in combat but not doing any real damage!

Mostly works if you're group leveling or bossing, where you can stand back for a couple of ticks after you fall out of combat.

Freeze or run around the mob in hope of it casting a skill with long cast time and getting the odd tick.
