Nukem/DE vs 3xHS A-Rails PromX are relatively equal in dmg output through the game with gunships doing more Burst dmg spikes (or you can have bigger range, but will lack on DMG comparing to PromX), where PromX will excell in constant dps pressure ( PromX does pretty much same dmg that DE/Nuk under Aiming Overcharge, with NO cooldown, and PromX under Valk falling a little short behind DE/Nuk with Aim AND OverDrive), of course there are situations and conditions for one or another,
But one of the main things going for PromX, while having very similar DMG to DE/Nuk it is still COMMAND ship with all team benefits to it - Valk (can be used for selfish reason and affecting your team or for your team), gravi scanner - those countless games I won by clutch use of this speed buff for my team, resist aren’t that big of a deal, but they are there.
Another thing is that with single Passive armor(combined with awesome passive bonuses)on Promx +1 Galv combined with hull aura, you have good tank, it is not like it sacrifices everything for dmg, absolutely not, so with D-Shield PromX can completely negotiate good chunk of incoming dmg, while GunShips do not have this luxury, Reboot is awesome but it does not provide as much sustainability in the front line as what D-Shield gives you, especially flying SOLO, you get the freedom from engineers. Of Course there are focus fire cases and ECM, but these are rather affected by knowing your limits and situation awareness, but in general PromX does not need healing as often and as much gunships do, i.e. independent sustainability.
All of this is not exactly to argue what is better (even though i find PromX SOLO have on average higher potential to win you game than DE/Nuk) but rather to point out, that simple statement DE/Nuk would have done better job is not true and has much more edges to it.
P.S. only thing that works for Wolf-M is extreme bubblegun mobility, but DMG wise and team presnse it got nothing on this PromX build.
Aura has 2x Hull slots, Sword S will have 1, capacitors are ignored because all of them go into D-Shield.
So Aura will have over Swords:
1x Galvanic + 40 resist from Hull Aura (Swords S shield aura is 36?) + (most common DMG in Sec Con is thermal and EM) Higher Default resistances to Thermal and EM + Smaller hitBox + “Instant” Heal from Hull Booster (CD discrepancy is partially negotiated by R13 implant, naturally better affecting longer cooldowns)
Oh and throw in average amount of Repair Stations around vs Charging Stations
Disbalance comes from Aura able to do considerable tanking AND D-Shield Tank, Swords can only have 1 or another due to the passive module layout.
