Warrior Aggro (Wave/Infes/Wess/Frosty)

[Kavious]

Ive been using Wavecrasher (Primary only) with Infestation in offhand. I like the double sword look and I figured this should be solid to level up with in groups.

Then one day while in a mid 40s group I had someone claim that they have one of the top warriors on the server and questioned my weapon choice. He asked what other weapons I had, which was a WESS and a Frostbringer. He told me I would have a significantly easier time holding aggro with Infestation mainhand and Frostbringer in offhand. His reason was that Infestation procs more often than Wavecrasher.

Parsing/Mathing and Min/Maxing not really my forte. So I'm curious.. Is there validity to his claim? Would Infestation/Frostbringer be significantly better than Wavecrasher/Infestation? This would primarily be for leveling up in XP groups
