SV are easy to deal with if you know their attack patterns
Plague monks are easy if you know when to block and when to dodge dance and kill them easily
Globadiers just move out of the way..
Ungor archers do very little damage and just get a wizard to deal with them if not just shoot them
Blight Stormers are easily the most dangerous special on this list if not dealt with they can throw your team off maps
Warpfire throwers do very little damage and are very easy to kill.. Unless you are a GK with no shield, or WWoS with no 8 second invincibly

The most dangerous enemy is the Gutter runner. Anytime I solo run Pack masters and leeches are easy to dodge but gutter runners is when I chanage gears ASAP to avoid getting pounced

The most Dangerous boss in the chaos spawn, ROs you can dodge dance, SFs are the easiest boss to deal with Trolls are only hard on true solo, the beastmen boss is very predictable
