How about greater range for the Aphelion? Considering hitscan and instant travel time, an increase in range seems really useful (unlike for the plasma weapons). Maybe put it instead of stability? And speaking of stability, how critical is it for the Aphelion?
Also, scope? Or are the other mods more useful?
Final question, what are your mod suggestions for a PVP suit?
G5 does 4.7 dmg wich is biggest dmg of all assalut rifles but without HSD, it aint does any extra dmg by headshot. Greater range is not really that much usefull on this weapon as 70m is long distance already (3nd highest base range of all, its more than enough), dmg falloff dont seem like big (its small), and with HSD instead, you will be able to get higher dmg (after shields are done afta few hits even at max range), even after 70m, than with greater range, if you aim at head, even at target at very end of laser range at 150m.
For targets that are like at maximum laser range(150m), you need maybe one more hit, to kill thier shields without GR, and im my opinion, for this mod is overrated for sure that weapon...
Stablity works wonders. It allows to full auto, even at targets at max range at 150, you can keep aim at head (without it, you will have to correct after each shot, makes full auto more difficult to do at full ranges), and no matter how well they move or dodge, unless they hide behind something, they wont be able to dodge it. Thats where strength of dual twin G5 aphelion setup is that uses both stowed reload. You can spam that laser, almost as if it would be LMG, as when first lasers runs of its 38 shots, you change to second laser, full auto that another 38 mag, and you can continue until both lasers runs of ammo, and it lasts for quite long time. G5 HSD P-15 helps dealing with more closer targets if they manage to get closer.
Scope helps with aiming those more distant targets, but its not really "must" have like HSD, stability, mag size. Stowed reloading is good too, but only if used with "Twin" setup.
So yeah, I use two varaints of aphelion, of total 3 g5 I have, of this wep.
For mixed combo, with kinetics or if there is no second main wep; HSD, Stability, mag size, Scope.
For "twin" with 2 same G5 aphelions as main; HSD, Stability, mag size, Stowed reload.
My 2 main PVP/PVE dominator suits either those two ones;
First: Jump assist, Extra battery, Extra ammo, Night vision.
Second: Dmg reduction, Extra battery, Extra ammo, Night vision.
Those are almost same, one is "mobility" focused, while other is "armored" focused.
I change them on depend if I would like to stay mobile, and jump assists helps a lot with that (you much more evasive and able to climb buldings faster, well as faster parkour too) but sometimes better to have dmg reduction instead, especially for direct fire exchanges, as this small diffrence at dmg taken can allow to come at top during fire exchanges.
Rest of mods are "must have", NV is standard on all my suits, as I like to hang out all over bubble, and it dont matter if its night or not (flashlight gives also your position at night during PVP). Extra battery allows to not recharge as often, and its always good to have extra ammo, as not always you are next to crate, and you dont wanna have a situation where you ran of ammo, and you cant refill it.
