That 18 DP "survivable" ship frequently struggles with survivability, since it's a bit too slow against ships with mobility systems.
literally the 2nd fastest human cruiser in the game, only beaten by Fury
it has 80 max speed, which ties it with Heron, Aurora and Falcon, but it has acceleration stats of a Fury, and 12.5% higher deceleration stat than Fury.
(for comparison Aurora's acceleration stats are 50% lower than that of a Fury)
I specifically mentioned mobility systems. There is a huge amount amount of ships with burn drive, plasma jets, maneuvering jets and phase skimmers that can hunt it down. Backpedaling speed of the attackers is irrelevant.
IME, it needs to run overfluxed to be effective (Paladin is soft flux) and even if temporal shell isn't on cool-down, it may not have enough flux to activate it.
I can get 1.5 Medusas for the DP of an Anubis. They have much better mobility and can be extremely dangerous (needlers + phase lances seriously hurt - shields up or down). The AI is quite competent with using the phase skimmer and makes far better use of it than the temporal shell. If I give a temporary eliminate order against a capital ship (to flank and assist or to relieve pressure for someone else), Medusa will be able to tank and escape.
Anubis having Paladin against fighters and missiles does nothing for my fleet (except for the Z fight). Yes, I'm using Locust, which you despise.
