I'm sorry but if you truly are a rogue in full S4 and you have twin blades and the retri pally was in greens (and therefore not pvp gear) and he got you in 4 hits, you must have been naked or afk. Some sort of exageration is at play here.
He said he was in full T6 and PvE specced which means probably 0 resil at all.
And for the OP, it's "glaives". I hate being the spelling nazi but it's in my nature. Many apologies.
