Your baseline is pretty conservative. For example, my fighter's at-will does 1d10+12 at 10th level and, fairly often, 1d10+21 at 11th level. (Marked Scourge, Son of Mercy)
Yes, I know the numbers posted above are conservative.
But that's because I don't know how to estimate or calculate the damage progression of PCs.
For example, from what you are showing, you have two sources of extra damage: a feat that adds a secondary stat to your damage 1/round, and a class that adds your secondary stat to your damage vs marked foes.
Is this something all PCs can have at paragon? All non-strikers?
I don't know the answer of the above.
If it is, then it should be added to the numbers above.
If it's not, then there are huge imbalances on damage progression as you gain levels, and should be addressed.
Also note that I'm assuming a 1d8 as the base damage roll.
In case of a defender, this is assuming you are wielding a longsword and a shield, for example.
So these numbers don't take into account superior weapons, weapon focus, etc.
Yes, they are kind of a baseline.
But I wish we could have an average/reasonable/typical and a maximum progression as well.
My barbarian does about 1d12+2d6+15 at 11th (or 14th...)
Note that the above numers are for non-strikers.
My warlord might only do 2d10+13 or so with an encounter power, but it's giving the rest of the group +6 damage per hit or +5 attack and damage with all at-wills...
Leaders are tricky to account for.
The 14th bard I just made only does 1d6+9 or 1d8+9 with at-wills, though, it's true. And that's as low as it can possibly get since I took nothing at all for damage, and hits your number for at-will.
Great, at least something's right!
Note that even with these low numbers, the expected number of hits to bring down a creature of it's level isn't that big.
We are looking that 20 rounds are the MOST you can take to finish an encounter. That is, assuming you need 10 hits to bring "your creature" down, that you have 50% of hitting, and that you have no strikers on your party and that your party does minimum damage.
Even with the huge progression of hit points the monsters have.
Heck, my assassin's Shadow Storm does 1d10+10 (11 with CA) at level 4, if the target's by himself.
Remember, only non-strikers posted above.
Note that if you remove your extra damage for been a striker, your minimum damage should be in line with the above list (and not counting improvements from feats, etc.)
My group's 10th level barbarian does 4d6+1d8+13(32 avg damage or so, not counting to-hit %) all day with Howling Strike charge attacks (which he manages to pull off 85% of the time or so thanks to Boots of Adept Charging - it would be more like 95% if he got a Badge of the Berserker).
Ditto.
At the other end of our group's spectrum, the Healing-specialized cleric only does about 1d6+6 with Sacred Flame...
