I'm curious to know how many people out there use ground weapons *other* than pulsewaves. Yes, we know, pulsewaves are pretty nifty, but there's a lot of other options!
For everything that isn't borg, I roll with an auto-rifle and a compression pistol. These weapons have a similar sort of intermediate range, and complement eachother very well.
Auto-rifle: Medium-long range on the primary attack, very high rate of fire, with a cone expose attack that has no appreciable activation delay.
Compression pistol: Solid intermediate range weapon, very high rate of fire, its exploit does "most" (80%?) of the damage of a sniper rifle but the activation and recharge time is much faster.
So, typically run and gun with the auto rifle until somebody gets exposed then switch to my pistol and give them charged shot. The guns have similar DPS so there's no pressure to switch back once the exploit shot is taken, unlike a sniper rifle which has fairly low DPS. You can pull your sidearm for the exploit, and keep on shooting without hurting your damage output.
I change it up whenever I get bored with different weapons.
Assault Minigun + Split Beam: Laying down minigun fire and following up with a split beam attack yields wonderful results. I use this mainly in colony invasion along with fire team.
Dual Pistol + Sword: Works nicely for close encounters. Used mostly with operative for stealth attacks.
Blast Assault + High Density (both with knockback): Something I started using awhile back for support, mainly in The Cure ground.
Anti-Proton Carbine + Compression Pistol/Sniper: What I use against the Borg. Expose targets with carbine, finish with pistol or sniper depending on what's needed. Used with fire team or operative and full Omega set.
Are you surprised? Shocked? I don't use a pulsewave against the Borg! Trolololol! I started using this after seeing idiots with pulsewaves run up to Borg in STFs, thinking they're pro-l33t, only to be wiped out by tactical drones. I've yet to see anyone outside of my fleet use pulsewaves without getting killed...a lot.
Minigun. They rip through anything except Borg, and with the Omega passive that slows adapatation, they're almost as good on Borg.
Ever since that patch that buffed that passive, adaptation has been so slow for me that it hardly matters. With a sniper and pulsewave I went through an entire elite Infected with only two adaptations and never having both weapons locked out at once. With a minigun in regular missions (elite difficulty) I'm only hitting adaptation every 2-3 groups.
Defo the minigun on my KDF Tac officer. I dont even unequip it vs borg (needless to say they adapt fast against so many little shots) but its just to badass not to use. But yea i love the Pulsewave on my Fed Science officer (sorry!) Its just to much fun.
My fav are the splitbeams, they deal a lot of damage up to three targets at long distance. A tac with fireteam can vap three targets on a lucky crit, And the splitbeam has a low cooldown as well.
O'm also fond of the sniper, more damage against single targets then the splitbeam, but with the general spam of npcs, anything that can kill more then one target at a time is preferred.
