Stupid thing as well is the XP is probably the easiest thing for the developers to fix. I suggested a change to XP which would have a rolling score for all your contributory actions which is then multiplied by a Winning and Losing multiplier at the end to promote actually winning the match as being important to your XP gains. Even with a change like that, you'd see Rhinos better looked after, because players just looking for kills would suddenly see their XP gains diminished because they're actually hurting the team's chance of winning through their selfish playstyle. Even without this system, the two least rewarded (yet two of the most important) tasks are babysitting uncontested points and babysitting transports. There needs to be more incentive to do these.
