The more you buff ranged damage, the less viable melee gets. If you do the math of the DPS of a firefight between Eldar and LSM, melee is basically completely annihalated by the time anyone gets within 20ms of each other. The ASC does already have a mid-range option in the form of the Impulse Accelerator. The ASC atm feels like the only Tactical Weapon in the game that encourages players to fight both at ranged and melee. This honestly should be the gold standard of Tactical ranged weapons. Instead of aspiring to buff everything to Bolters, look to the ASC as the example. A fact that's hugely important is that the ASC does not handle Toughness very well, thus forcing players to use different weapons against tougher targets. This is asymmetrical balance, and the Bolter, Stalker, ect, pretty much ignores this, even though Plasma is supposed to be the answer here - it's hardly used, whereas the Eldar literally have to change their team composition.
