Because slow moving Heavies (even Militia) can fit a proto Rail Rifle (for example) and DOUBLE their effective kill range without losing any effectiveness in CQC as they also have enough shield/armour to overcome the very slight warm up time of the RR.

Right. And this string is about Heavies fitting non-heavy weapons. The RR was one example. Get over yourself.

I hate giving this manner of nincompoopery the time of day any more than I have already, but here we go:

The reason heavies can use light and sidearm weapons in their heavy weapon slot is because the requirements to use these weapons are quite simple - hands. So why can't the other suits use heavy weapons in their light slots, you're about to cry? Because the heavy suit was designed to augment the user's own capabilities further than the other suits allowing someone using said suit to carry heavier gear while still being able to, you know, walk.

And walk we do, cryhards - we walk around at the speed of smell, whether we're using an HMG, an AR, or nova knives in our H slot, because the sentinel suit was designed specifically for the carrying of ridiculously heavy weapons that otherwise would be mounted on a vehicle - seriously, it says so right in the descriptions for them - so technically a sentinel using a light weapon is gimping himself. While that's not the case atm because of OP light weapons, that's also not the fault of the heavy suit.

As for heavies with light weapons encroaching on the territory of commandos? MEH. Logis with over 1,000hp encroach on our territory just as much - Sentinels are supposed to be the most armored suits, yet logis can do our job better than we can given the OP state of RR (and CR to a lesser extent) right now (especially if we're talking about a sentinel using a light weapon), and yet sentinels can't carry 2 light weapons even if we're not using a heavy weapon, we move slower, and our punches don't hit like a train wreck. Oh, and just in case everyone forgot, we don't get any equipment either.

It really sounds like you're whining because a heavy with an RR beat you at range OP, or worse, you were using an RR as well and couldn't beat the heavy because of the hp difference, despite the fact that hitting a heavy in the head is about as easy as throwing a rock into the ocean and hitting water, and people in lighter frames have a decided mobility advantage. You do realize you can disengage from a firefight, right? Zerging in front of the enemy's rifle barrel is not the only tactic, even though it's about the only one Dusters seem to use these days.
