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 was enjoying plasma primary, grenade pistol and AM rifle the other day.
Killing hulks with slit-shots feels great and grenade pistol can hit factories from quite far.
Depending on other team loadouts I'll take airstrike or mortar or 500kg and shield backpack.
