The monster-building rules are very useful for considering PCs; by the math a PC should equal an Elite monster of that level, which means they should equal a standard monster of Level+4.
Standard monsters average Level+8 damage, IME Elites need to do 1.5 (High-Limited) times standard single-target damage as their baseline output in order to equal the threat of 2 standard monsters, with their AP that makes at least x3 damage for that round, possibly more if they have limited powers, minor action attacks, etc, but no monster should do more than x1.75 damage on a single attack, and that for Elite Brutes.
I have found that PCs should be expected to do baseline damage of around L+8 per round, same as standard monsters, but Strikers can do around 50% more.
On Monday I ran a session where one player played a well-built level 8 Archer Ranger, a top Striker, and another player a simplified level 8 DMG-2 Companion Character Striker, similar to an armoured Slayer, whose base attack averaged 17 damage (2d8+8), but who also had an AP, Heroic Effort, and a recharge 5-6 power strike for average 23.5 (3d8+10). I found that in practice the two characters had very similar DPR, the Ranger was only slightly ahead, and the Companion Character was generally ahead of a second less optimised Ranger PC in the group.
My overall impression was that the Striker PCs were doing around 1.5 Level+12 or 24 damage on a typical round, while non-Striker PCs average Level+8, or 16 at 8th level, and this is similar to Elite vs Standard monster DPR. But a player of a normal PC has to 'work to stand still', by making decent power selection choices etc, whereas monsters get their good DPR 'for free'.
