I want to share my comments on builds, from PvE point of view. I will make references to CBS planner cell coordinate system to make it shorter.
Ophelia - the "meme" build I saw somewhere either on Russian forum or RU discord, early once this commander released and I stick to it up to present day. PvE mostly about damage and this build won't disappoint you. http://csb-hype.5v.pl/?ophelia=A6A7A8B1B7B8C4C5D4E4F4G1G2G3G4G5H5
Erin - If ramming is nor all day issue for you, I suggest swap F3<->F4 and use this http://csb-hype.5v.pl/?erin=A1B1C1C4D1D2D4E2E3E4E5E6F3G3G4 Better cooldown of trait means you get more cycles of stuff like supercharged APS - example of one of most useful things
Miramon - I use same build which i probably it saw first time in some old SRY vids, well that is as old as commander build system in AW. http://csb-hype.5v.pl/?miramon=A1A7B1B7C1C7D1D7E1E2E3E4E5E6E7 The case is you pick E5/E6 cells for better smoke reloading.
Douglas - My recommendation is to stick to the "visual range + slightly different" which maxes visual range, then the repair as second stat in PvE. http://csb-hype.5v.pl/?douglas=A1B1C1D1D2D3D4D5D6D7E1F1G1G2G3G4G5
Sabrina - i try to maintain durability-stealth balance because of the need to use this commander on both Challenger ATDU / PISH and Wilk XC / PELE - to complete "fire" tasks. http://csb-hype.5v.pl/?sabrina=A1A5A6B1B6C1C3C5C6D1D2E3F1F2F3
Freja - For a while i kept her strictly for artillery, so max investment into accuracy, then aim speed. http://csb-hype.5v.pl/?freja=A1A2B1C1D1D2E1F1G1G2G3G4G5G6G7
Sanna - I have mixed feelings about its "fire" performance in 0.35. But even if you won't get that much damage from fires, it scores a lot of XP points for spotting. http://csb-hype.5v.pl/?ioannis=B1B2B3B4C4D4D5D6E4F1F4G1G2G3G4
Atassi - I saw this build on Chavez channel (RU streamer) and I use it myself, mostly on things like Hellfire or AFT-10, superior DPM and fire instigation. http://csb-hype.5v.pl/?rashid=A2A3A4A5A6A7B7C7D4D5D6D7E7F7G7
Cortez - Only pick perks which i know i need them. http://csb-hype.5v.pl/?cortez=A4C3C4C5C6D5E2E3E4E5F3F5G3G5G6
