I would say that boating, as I understand it, just means carrying mostly or all lrm launchers with few or no other weapons. It makes no difference whether these are lrm 5's or lrm20's. In point of fact some Mechs were intended to "Boat" since their primary mission was fire support. The MadDog and Archer are very good examples of this, and therefore they will inherently have more LRM hardpoints.
The preference for LRM5's in multiples is mostly a function of recycle time and spread. LRM5's recycle faster so mathematically they can actually put more missiles on target than larger launchers. The spread factor contributes more to components destroyed and kills (because so many groups are coming in so fast) more than it does to overall damage. More missiles ultimately do more damage. (3xlrm 15's do more damage on average than 6 x lrm 5's. 4 by LRM 20s is obscene when they hit together, its just gonne be forever before they can fire again.
My preference for LRM5's is mostly driven by ammunition. With LRM 5's I have more control over the rate at which ammo is expended. I like being able to fire off a five missile volley to make a sniper duck, or see what the AMS coverage is like. Even if they accounted for recycle and spread, I'd stick with 5's.
I would support direct fire only lrms if they behaved like lrms do in TT: they are fire and forget and move as fast as any other projectile. The only way to avoid getting hit would be a duck behind cover, otherwise the missles home and hit. No need to keep a lock..just get one and fire. However, to compensate for the lack of indrect fire, an Arrow IV system should be added to the game, making it very costly to sit behind a ridgeline and play peek and poke.
The reality is indirect fire adds a potent weapon to the game as it forces opponents out of good positions and makes them take cover. However, when lrms were powerful, everyone complained about LRMAgeddon and thus they got nerfed.
The sad truth is LRMS are only dangerous to players who make a mistake and get caught moving slowly in the open. There is really only one map where they are potentially decisive, and most top players think of them as relatively useless. This all this complaining about the lack of merits of LRM 15's or 20's amuses me. If you are really worried about being good you won't bother at all. As I tell people when I get the "LRM NOOB" whine in game -
IF YOUR *** DIES TO LRMs IT IS YOUR OWN DAMNED FAULT. You didn't take cover when you heard the waring, your didn't bring radar derp or AMS or you left the lovely bubble of your teammates ECM. Show me any other weapon in the game with so many possibilities of evasion or countermeasures.
I play mostly LRM boats so I disagree (somewhat) that LRMS are useless, but in all honesty I enjoy the head game of playing LRMS correctly - I am looking for guys who made a mistake. Also, I seriously suck at ballistics. The last thing anyone wants is me on their team in mech with AC5's or 10's
