Are people seriously arguing that the Enforcer isn't good? It's one of the simplest and easiest classes in the game, especially with Sacrifice enabled. Anyway, Loader should be a pretty simple class to fix: Speed up Knuckleboom and give every hit a small stun. Fix the speed boost from Debris Shield so it actually lasts three seconds. Give Hydraulic Gauntlet some kind of buff, anything really. Maybe have it deal a little damage and knock back any enemy you pass through while grappling. Also, having it shoot upward at an angle while airborne would at least make it easier to use for its intended purpose. Fixing Hydraulic Gauntlet would also fix most of the problems with Conduits.
