There should be various levels of difficulty on caravans, with the way caravans are now as the most difficult. Please don't just gimp these awesome hard caravans because so many people say it's too hard. Look at Ares - it's too hard! Yet Seki showed us how to solo the place. (Good job, Seki).
So i don't want to lose these ultra-difficult caravans altogether, but i agree the way it is now is very very very tough. Example: Venger tried one solo today. He was using a special Avenger minigun and 3xBRD, ready with stimpaks on hotkeys. (Watched Seki's Ares video and been there a few times practicing. Getting better too! Almost cleared the surface solo with an EW sniper). Anyway, 2nd encounter is the robed Colt gang. Venger ran up to 1-hex a target, got 1 burst off and was immediately knocked down and out, his target still standing there. All that training and all his readiness was worthless once Venger was knocked out. Death on 2nd encounter with no kills. Caravan totally lost - enemy took no casualties. (1st enc was 3 scorpions).
This is not exceptional. It is a typical example of how difficult caravans are now.
