Well playing solo or 2x Lone Wolf makes your gear better, beacuse u're using gear for 2 characters, not 4. Thats means you got powerful Lone Wolf perk and better gear.
I mostly find my gear, but always look at merchrants, sometimes they sell very, very powerful items.

Rogue and Shadowblade is kinda diffrent, shadowblade starts with Polymorph which allows him to use Invisibility smile
I going like that:
Backlash>hit>all in>invisibility>
1 free tour
Haste>Throwing knife>hit>Time warp
2 free tour
Hit>hit>hit>playing dead
3 free tour
again Backlash>Throwing Knife>hit

And if someone is still alive, he can do any damage to me after 3 tours laugh
Its overpowered, even at Tactican Mode laugh
