I feel happy with my loadout vs bugs. Spray and pray is easy to understand. Run and gun. I'm not as confident with bots.
Loadout: Armor is medium with crouch aim bonus. Base gun, the Adjudicator (assault rifle) from Democratic Demolition because of its armor pen. 2ndary is Autocannon and ammo backpack. Strategems are orbital laser, eagle airstrike, and mortar sentry.
All the advice I read is "go slower, avoid patrols, etc." and I'm fine with that but everyone I play with does the opposite. They engage EVERYTHING. I feel like I've got OK damage per shot, but everyone is getting there faster and killing things faster because they got there earlier. So I end up feeling like I'm not pulling my weight.
I agree with most of this. Laser is a great get out of jail free card.
I tried the Dominator but I didn't really like it. I went back to the Scorcher. I can still kill devastators by spamming and also scout striders by shooting them ~4 times in the front armor plating.
Redeemer secondary handles berserkers in a clip.
OP: It's worth noting that bigger units can have their arms or legs removed and sometimes that is easier than headshots.
Impact grenades also handle scout striders easily, and help with devastators, and you can still do factories by threading the needle into a vent - usually aim at the bottom of the vent opening - or by chucking one into an open door.
AC can do the same by ricocheting shots off of the vent cover into the factory.
That said, I just got stun grenades and am trying them out with precision strike.
