Well, here's where I'm coming from.

There are a lot of logs showing orcs not doing anything great.

Most of the orc kills, seem to be an attack of opportunity (eg, the orc caught someone at a severe disadvantage).

I read most of the logs with straklaw in them. He was always grouped, and he died soooo much. Seeing as he was the most famous orc chief in recent memory.. I assumed he might have some skill =P

There's a recent log of a midlevel druid killing (two) midlevel orcs (inside) of the grinning skull village.

The general trend that I see is that orcs get stomped.

Valguarnera said they were like (rangers or assassins)... but where is the stealth? =P I don't see pk happen much in swamps..
