As I already said, only way to make Great Lance useful is to make its only ability exclusive. Currently heavy lance is like swiss army knife, it can be used in every situation therefore no need for Great Lance. When I was playing lancer, more than a year ago before lance angle nerf I've used only heavy lance. No shield, no one handed sword as backup. I was pure lancer. I would like to see lancers who use thrust-able lance like Heavy Lance and couch-able lance (Great Lance). But in that case they would be raped by ranged. So it's needed to make ranged non "viable".
