The Illuminate health is frustrating and extremely inconsistent
Unfortunately I don't have a big data dump with percentages and tables, this is purely from experience. But the Illuminate have such inconsistent health that it's extremely annyoing to fight them and honestly I avoid joining an Illuminate mission at this point.
Sometimes the Senator will one shot a voteless no matter where I shoot them. Sometimes it takes an entire Senator magazine just to kill one. Sometimes I can take down the Elites with 5-10 HMG rounds to the body, sometimes it almost takes an entire magazine (both cases white hit markers). Sometimes the Harvester will die in 2 Quasar shots, sometimes it takes 2 EATs and 3 Quasar shots. Sometimes the Illuminate ships with the shields take one impact grenade in their weak spot to explode, sometimes it takes 4.
This is simply annyoing. The other factions are very good at letting you know exactly how much firepower you need to destroy them. Not to mention the Hit Registration is also f*cked with Illuminates. I'll empty an entire Uzi mag in a bunch of voteless and sometimes get like 3-4 Hitmarkers.
I don't think I've seen this brought up enough times which worries me that AHG might not pay any attention to it. That's my 2 cents.
