The Titan exclusive auto rifle "Fabian strategy" is very underpowered compared to the "tlaloc" and "ace of spades". Planet destiny released a well made review of the Fabian and how it performs after its "buff" in December. The main problems occur around the exclusive "front lines" perk and the weapon class and archetype. Auto rifles as a whole are in a strange no mans land where hand cannons and shotguns can outperform them at close range, fusions and pulses at medium and snipers and scouts at long range. The Fabian relies on you being close to enemies to work but it does not do enough damage to counter a shotgun warrior. By the time the front lines perk activates you will only have half a magazine left and will just change into a doctrine that has poor stats and no counter balance. I would like to see it be buffed to work alongside sunbreaker abilities or front lines to increase rate of fire AND impact.
