It's a complex problem, OP. Me, I'll always try to help the unfortunate 'wave clutcher' with whatever tactical advice I can - but advising missile strikes is something I'd do only if the clutcher needs that sort of advice. That is, if it's a competent pro playing at around my level of skill, well, I'll leave it them to decide. If it's someone that doesn't have a lot of experience with the solo skillset I will tell them whatever they need to know, including when to missile, when to gel, when to stay down so the phantom stops dancing on their corpse, etc.
In a more general sense, though, I must admit that I have little empathy with missile misers. I just cannot see the game that way.
When I go into a game I always understand, however unconsciously, that I have 6 missiles/gels/ops packs/clips and assume that those items (along with single use mods) are the "cost" of entry/admittance - the price of the ticket - into each 11 round bout inside ME3MP's magical theme park of violence. If, by chance, I extract with any or all of those still in my inventory then that's a nice bonus to add to the fun, XP and credits with which I am already rewarded.
Furthermore, regarding those credits, I tend to mentally allocate a portion of each game's payout toward the purchase of the supplies necessary for admittance into the next game. For example, if a gold game earns me 83,000 credits, I think of that as 33k towards a JEP and 50k towards the hunt for better guns (aka, my UR-gambling addiction).
Gear/consumables are, to me, the cost of doing business.
It is this understanding that causes me to feel varying degrees of irritation when a PUG drops into a Gold/Plat with me and puts on no gear - gear that might help their Avenger IV actually hurt something or mitigate the weight penalty caused by also carrying a Widow III or keep them alive long enough to get a couple of shots off before the Banshee grabs them right in the middle of swinging that f@&king Krogan hammer, etc. Why might I get angry when a PUG doesn't use medigel and then says, "I'm saving up for Arsenal Packs!"? Because they are refusing to pay for "the cost of doing business".
If you are counting on someone else to have the missiles/gels necessary for the success of the match then you are not just a 'leech', you are straight-up PANHANDLING.
Now, I get it that some folks - of sufficient skill - might want to increase the challenge/difficulty of the game by trying to succeed without using gear/consumables. I've got ZERO problem with that...provided that they possess the requisite ability to pull it off and don't let the mission fail in order to save a medigel or a missile. That's not a good trade... and that person shouldn't be played with ever again (and might need to be burned alive by Vorcha Master Baits so that their ideas/genes can't propagate). Frugality is fine and dandy (though seems kinda childish when you remember we're talking about a video game's fantasy currency) but being a missile/medigel miser makes you a douchetard...
...especially when JEPs are cheap and are guaranteed to contain 5 EACH of the basics.
