First I have to avow that I love to play chaos lance/carrier builds, but at the current state they are not really working. As I suggested in an other post one way to make lances viable would be to make reload also function with lances.
Reload: Imo reload is a damage dealer stance, the +66% of dps is awesome. The stance of choice for destroying hulls.
Lock On: First I would reduce the crit chance of lances to it's prior value. Then I suggest to increase the bonus of lock on for criting to 200% or 300%. With that change we would get a real stance for criticals.
With this changes you would have a real choice between brute damage or surgical strikes.
