Have you considered altering the health buff mechanics? Currently, with all five extra pips (30+25+20+15+10 = 100 extra hp), lights get nearly double their base health but heavies get only 50% extra or so. Making them multiplicative rather than additive (or maybe each pip adding a fixed % of base health rather than a flat hp value), or even just more effective for heavies could make them more attractive to play as but I guess this would only have an effect if the team is capturing command posts and buffing each other.
Heavy HP is absurd

Ye, a percentage value would be much better to not favor the light too much (SMGs and speed) and then health close to heavy. This reminds me of MNC with the Armor perk that gave you 300 health making the health difference between heavy and light classes marginal (was fixed later).

Stuff like this, that’s just great to hear 
A lot of people fear that devs don’t care to look at balance, they need to hear stuff like this.

When you 1 vs 1 another experienced player in close distance he will strafe left right left right maybe crouch too while firing and thats the main advantage of the lights in close distance combat they will strafe a lot faster and dodge a lot of damage , while medium and heavy have bigger hitboxes and won´t strafe so fast, imo the side strafe speed should be the same to all body types that would help balance it.
