Now, I know of the rivers in Cyrodiil(Assuming they are similar enough to Oblivion's Cyrodiil) and had been considering getting an Argonian PvP group set up that would be, as noted, a Waterway Strike Force, who uses the rivers to get strategic positions before coming out and charging for pincer attacks or simple ambushes.
However, then I heard most of the waterways were infested by slaughterfish and would get us killed by making use of them. Is this true? And if not, then how viable would this kind of tactic be noticing the Argonian increased swim-speed racial?
