Just curious as to how different players employ their skirmishers, and what changes you make to these tactics when facing certain factions and/or unit types.

Currently I have a Roman campaign and am busy hacking up the Britons. I've noticed that they almost always deploy all their infantry in one long line and attempt an envelopment, so I keep my velites and peltasts behind and on the flanks of my infantry at oblique angles, with cavalry posted immediately behind for a hasty fall-back.

How do you employ your skirmishers?
