I have heard much about the changes to skirmishers in the new rules, and to my (granted amateur) point of view, it seems that skirmishers are now totally useless for everything they used to do.
No more 360 degree
LOS means the cannot charge or shoot in any direction. I have a really hard time grasping this one; what, did they all get breastplates with helmets chained forward? Now that we use true
LOS, why is it that guys on one end of a skirmish unit can't just look to the side and... well, see?
Fixed 'semi-ranked' formation means that maneuverability is only slightly (if any) better than ranked units.
So with that in mind, what are skirmishers supposed to do in 8E?
Their traditional roles as flank guards gets severely compromized by their limited
LOS and the new charge rules (don't get me started...

). It's too easy to charge a unit past their
LOS and once there, there's

all the skirmishers can do about it. What's worse is that now there is no good way to guard against flyers getting behind your line... or dwarf miners... or skaven tunnelling teams... or beastman reserves... These are things that shooting skirmishers held behind the line were good at dealing with... and now they're not
Screening? Oh, wow, they give a massive -1 penalty to hit targets on the other side of the unit. That's... severly underwhelming.
Maneuvering through tight spaces quickly? Nope, now they move in formation. But they don't get any of the traditional benefits from formations, only the penalty of being forced to reform and wheel and what not as normal units do.
So why take skirmishers anymore? It seems to me a smallish shooty block will do the same job, cheaper. Am I wrong?
How am I wrong? Please tell me!
EDIT: I see rumors of 180 degree
LOS on another board. Is this extended to charging as well, or is it just for shooting?
