Canonically speaking, a general lack of power is also the reason phasers were tied in directly to the warp core for the TMP refit - to compensate and get more power allocation according to Decker, which is also exactly why they went offline during the wormhole sequence. When the M/A intermix is imbalanced, the phaser systems themselves might become fatally unstable.
I suspect that combat SOP uses phasers as a focused means to wear down a target's shielding, to be pounded by a secondary barrage of torpedoes to finish them off, the latter being not as effective as the former against cracking shields.
This is why future iterations of Phasers should have both "Battery Backup" & a direct connection to the Warp Core EPS conduits.
This way, if your main connection to the Warp Core goes down due to battle damage or whatever reason, you have a supply of energy from your "Battery Backup" to cover your weapon systems so that you can keep on pounding the enemy target(s).
I really like Torpedo's because they're heavy Burst / Area damage, that can be very effective when used situationally.
The main issue is with current Star Trek combat, is that it feels like it's stuck in WW1/2.
There's no CIWS or (Anti-Missile/Torpedo) interception weapons on any ship.
Which is opposite of how Star Trek Space warfare would proceed IMO based on IRL Warfare & Technological Progression.
The next big change to StarShip combat will be CIWS (Anti-Missile/Torpedo/Projectile/Remote Weapons/Drone) systems that are dedicated for that purpose on all StarShips.
The counter to CIWS is to go 2x paths:
1) {Stealth/Cloak} (Torpedoes/Missiles)
2)
Itano Circus / Macross Missile Massacre
3) Holographic Projectiles to help act as decoys.
4) Any combination of the above.
Continuation of advanced ECM Warfare with EM Jamming & ECM & ECCM.
Star Fighters will continue to gain importance along with Remote Drones & methods of jamming FTL travel to trap a target into place and continue a fight in local space.
Long Ranged Warfare will also continue becoming more & more important with less importance on "Dog Fighting" in space.
