Yes, EPC can one shot a huge cloud of mactera within its radius. Definitely don't be trying to waste flamethrower ammo on mactera, use your EPC. With the EPC build highlighted, you have more than enough EPC ammo to constantly deal with mactera.
I've been having problems with the Dash Perk, it happens to me that I press it accidentally when I'm escaping or things like that, by chance do you use hold to sprint on or off?
Excellent build, just 1 note is that 1st tier 2 choiche of the drills "mines faster", it never did anything since years, the buff is negligible and its so bad it looks like a bug that they never fixed. Choosing that is a net nerf because the other options give you the same and even better results. More damage works well if plan to use your drills as a weapon, wich works very well, and More fuel lets you mine more than faster mining would. There is a video of "Drilling in the name of" that explai
For Industrial Sabotage I use 23232 Scorching Tide instead of Sticky Fuel, as it performs close enough to Sticky Fuel against regular enemies, and it performs much better against robots, instantly igniting anything that can be ignited (all turret types, patrol bots, Caretaker appendages, etcetera). Alternatively, if you lack Scorching Tide, you can use Fuel Stream Diffuser, the longer range making it good against sniper turrets and patrol bots. It's usually built 23221.
little tough to get that hang of but once you do this thing destroys mobs. struggles a bit against armored enemies especially if you're in a tight space and macteras are straight up nightmares but it's a fun class on higher levels for sure.
