It’s comments like this that highlight your ignorance on basic class fundamentals.
In just one sentence you have proven that you do not understand the difference between DPE and DPS.
Predator builds fall short on long lived mobs do to the length of the fight, Less procs, less energy , less uptime on JF, etc… This is also true for st boss fights, which is where the BT/sabertooth builds shine. That explains why your sims, and it explains why top end ferals running higher keys opt for BT/ST over moc/pred.
On shorter fights however, such as trash pulls in mid range m+, Predator pulls ahead, granting us infinite energy and high crit from TF.
Ferals have two limits to their dps. Energy, and the gcd. Predator eliminates the energy problem. So the only thing holding us back from going nuclear is the gcd.
You simply cannot spend if fast enough. The game won’t let you. Now DPE is irrelevant. It’s all about DPS. Making use of every global to produce the maximum amount of damage.
So back to this …
But if it does less damage than a swipe according to your logic you would be wasting a gcd. Just like how using an insant regrowth for a bloodtalons proc to buff your damage is a waste of a gcd too, right?
Wasting a gcd on a heal so that you can buff your next 2 attacks by 25% at the expense of a full attack is a dps loss in this scenario. That heal essentially did 50% of the damage of what swipe could have.
With back to back predator procs, If the mobs are close to death and you already have rip applied. Yes. Swipe away.
As proven, It does more damage.
But this is a case by case scenario and generally no, You want to dump those cps, and use the free attack.
