Generally, I try to keep my Felstomper at Intercept range if I get chance, so any Warrior heading my way either gets Intercepted first, or Counter-intercepted towards the end of the stun period so I get chance to cast something.
Curse of Agony/Corr/Shadowburn to start with (I don't mind burning shards) Death Coil and apply Immolate. I'll start to cast Searing Pain and if it doesn't get pumelled - great, I'll spam it. If it does, Fear, Searing Pain and keep close enough to try and avoid another intercept. Drain Life, another Shadowburn and I can generally take down most Warriors 1 on 1 (Lucky hits aside).
I've even taken two at once, but I was lucky enough to be next to the restoration node, with an Adamantite Bomb up my sleeve
