what's destroying the Edelweiss? Is it getting in front of the super tank?
Well regardless, once Sylvaria is around you need every person to be out of sight. Hide your lancers in the trench on the opposite side of the map that the supertank will pass by. Anyone that's out of that trench should be behind your own tank. Really it's just all about keeping everyone out of her sight, no matter what it takes. Sylvaria will usually stay around the supertank or your tank (during my matches my tank was always near the supertank) so her movements are usually easy to predict, and if she can't see anyone then she won't even use her movement.
