LRMs are an odd thing. Long range missiles that fire in an indirect arc, that require locks (or no locks, if the pilot can manage leading and estimating), and have the potential to saturate an area with damage, though on a smaller scale that artillery strike consumables and with greater precision. However, LRMs have always been a bit hard to work with in balancing; Some players loathe LRMs due to constant bombardment, and not liking people building LRM-boating 'Mechs, while other players see no issue with LRMs, and use them as they please.
Speaking of pros and cons, LRMs do have many weaknesses. AMS mitigates, and in some cases eliminates, LRM damage. LRMs require a clear firing arc to allow for all missiles to fly to the target without impacting terrain or other obstacles. LRMs will always fly in an arc, making it difficult to fire at a target at some angles. LRMs also require either the target to be spotted and locked by at least one ally, or the LRMs' shooter. There is, in addition, the minimum range of LRMs, which do 0 damage within 180m for IS launchers, and heavily reduced damage within 180m for Clan launchers. However, LRMs are the only weapon system capable of indirect fire, and locking a target greatly increases accuracy. LRMs also have a range advantage, and are capable of hitting targets up to 1000m away. As it stands, LRMs are used primarily for their indirect fire to hit targets at medium to extreme ranges, and are often carried in a small amount of large launchers, or more often in large amounts of smaller launchers. In many cases, it would seem to be that LRMs are mounted on 'Mechs that primarily use them, usually with very few or no backup weaponry, or LRMs are completely ignored in exchange for greater direct fire capability.
Well, what if LRMs could be fired in not just one, but two ways?
My idea is basically that; LRMs have the option of switching between direct and indirect firing modes. (I know something along these lines are currently in the works, as the devs have claimed to be trying to make Clan LB-Xs capable of acting as standard Clan ACs.) Either method of firing has its own advantages:
Indirect Fire
- Very similar to what we have now
- Allows for indirect, arcing shots
- Lock on to targets for far greater accuracy
- Features a slightly lowered missile speed
- 'Mechs can use this to maintain fire support
- Can be used in a more defensive method
- New firing mode
- LRMs fire in a directly at the target, similarly to SRMs, but with LRM properties
- Targets can still be locked
- LRMs maintain their minimum range
- Missiles, once fired, can make small course adjustments
- Features an increased missile speed
- Would allow for LRM usage in previously impossible areas (Such as tunnels)
- Can be used to make LRMs much more offensive
- Possible change: LRMs do not fire in large swarms (IE: LRM40+Splat-Cat)
