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 try to branch out but almost always drift back to something like:
Regular Breaker
Autocannon
Walking barrage
Eagle airstrike
EMF turret
Bots are easy until you get into level 8 games with the Solo Sprint Brothers that aggro the whole map.
