The current missiles are Semi-Active Radar homing which is fine but it doesn't lead to a lot of variety in the missile segment of the weapons tree.
One great idea would be HARM missiles, explicitly missiles which cannot be independently targeted but when fired would fly towards ECM Mechs, mech's TAGGING you or mechs which have you locked. This would be a good option to add more depth to ECM play. Thy should do only 3/4 of the damage of regular missiles though. If you fire them and there is no ECM mech or enemy targeting you then they are wasted.
Another option would be Active Radar Homing, you only need to get the initial lock and after that they are fire and forget. They do half the damage of regular missiles to make up for the easier use .
Infrared missiles are also an option, some operation as regular missiles with two changes. No indirect fire (LOS only), but lock time is reduced the higher the enemy's heat level. Slightly faster then regular LRMS' to make up for the lack of indirect fire.
