So BoLS did a couple articles on foot lists- or perhaps I should say that Goatboy did them (here and here, respectively.) He has the core of a point- in a mech-heavy environment, a foot army can have advantages by virtue of opponents being unprepared to face it properly. The problem, however, is that he makes the mistake of not going for foot lists that have all the critical advantages while avoiding disadvantages. There is a reason mech is king: it provides these advantages relatively easily. In order for foot to do well, it needs to likewise use them. This also has to do with BoLS' understanding of the game and believing in a metagame. Pure mech and foot lists have an advantage over other lists (particularly foot lists) as some of their weapons are essentially useless. Mech has this to a less extent than foot as there are always some foot elements to a mech army, you just have to get them out of their transports. Anyway, a lot of readers there seem to believe that taking non-mech is going against the 'meta' and gives them an advantage. Against lists 'metagaming' (i.e. tailoring) against mech lists, yes this gives them an advantage but against balanced lists? Not so.
Number one is mobility- missions in 5E want you to move about to take (and contest) points; getting into better positions to dictate charges, take side shots, bypass cover, etc, are all important factors. If a list doesn't have mobility, it is doomed. Mobility can be more than just moving over 6" per turn- it includes the list's overall ability to take points and get to the enemy as well as its reach/threat and deployment options.
Number two (WHO DOES NUMBER TWO WORK FOR??) is protection. When you're inside a metal box, you can't be hurt. Period. Obviously foot lists can't duplicate this, but they need a way to increase resilience above just "3+ armor/4+ cover". There are lots of ways to work this, including MSU options, resilience through numbers, etc, but you can't just be a bunch of bodies on the ground.
