But yes, more crit seeking that hole-punching.
I don't see it as a crit seeker either. To me a crit seeker is a weapon that will take advantage of exposed holes in the armor. Unless you're using LRMs to backstop ERPPCs, Gauss Rifles and Clan Large Pulse Lasers you're probably not going to use them in that role. More than likely you're using them to bombard the targets initially and soften them up.
I was just pointing out the PSR reliability is better w/ a single rack.
In a discussion about absolutes, yes. You can force a PSR with a single LRM20 rack than a quartet of LRM5s. With the inherent unreliable nature of missiles strikes, even your best chance still isn't a good chance.
Though, I am now pondering what units out there only use a single LRM20 in 3025.
