I'm trying a dedicated murderhobo: Juggernaut + 10CON blade, blade & evasion tag, combat option nearly every time.
One question is whether evasion is worth investing in combination with armour, or you might as well only do armour, and for me the key is how much Reaction contributes. So far, evasion's been important since getting some good reactions is the key to solving the turn economy problems for 1-v-many fights, but we'll see for later game. About to try Bart.
I'm pretty convinced blade and pistol are the kings of weapon types for solo, but am hoping to try SMGs again, etc.
I'm also doing a murderhobo with blade.
In my view, you need both evasion and armor. Do you mean picking the feats for evasion over armor? I think early on you need high evasion so that it continues to grow.
But evasion is not enough on its own. Even with extremely high evasion (90+ early on) you'll still be getting hits fairly often if it's a big group of opponents. You'll only start evading in earnest with the force field, but it doesn't last long for you to cull the enemies. Maybe in the future when you get the cloaking device, it will be better. Although a smoke grenade makes things easier.
Also even with all the armour, you won't be able to straight up kill everyone in face to face combat. For example, my guy has to resort to sneaking for favourable positioning. I don't want to make him pure solo in the long run though, so I'm not picking lone wolf. I want him to be solo until advanced companions, then I'll get one. I did consider doing a melee duo with Jeb, but decided against it because he is a Negro, so it clashed with the theme. I also considered a duo with a tanky Faythe, but she just isn't strong enough, so she'll end up getting killed all the time and I wouldn't be able to make use of staying power.
In terms of armor, the church companion was built around that and he was very strong.
