These skills do nothing except some troubles for their users sometimes: Triggered too often and thus, can be called instead of a good offensive ability. It's an analogous of "Feint", nothing more.
Using both, net and whip we'll get too "chaotic" Entangle. Perhaps, there is a sense to use off-handed whip instead of net. In order to get more offensive behavior.
While we are trying to use both of styles in every fight we need to find good switching system. Since there's no triggers like "All of my offensives in cooldown" i see no way to use both of them correctly.
