Based on the tribble patch notes we can expect that with Season 10.5 the [DMG] mods get a update.
Instead adding a cat 1 damage bonus on the base damage of the weapons the new [DMG] will apply the a damage bonus AFTER all other Buffs. That means even AFTER Cat3 or Cat 4 buffs (Sensor analysis). Additionaly to that it was announced that the damage bonus gets increased to 3% per mod (which is stacking).
In best case with a [DMG]x4 + [AC/DM] you get a 15% bonus on Top of all other damage Buffs.
Compared to the old way [DMG] worked this is a massive improvements which clearly renders these types of weapons much more useful.
Their damage output might be short behind of [CrtD] weapons and especially ship builds based on low crit values (without many tac consoles or tac slots without Superior Romulan Operatives) will benefit from this change.
An interesting side effect might be that players might use Adv. Fleet weapons to create a relative good DPS build (as there are versions with [DMG]x3 + [CrtD]).
