Ok, lets say lvl18 Ez is fighting lvl18 Ez.

Base Armor Ez18 = 71,5 MS Damage with ~140 +AD from Items = ~350 physical dmg

Now the damage scaling 1) no armpen 2) 15 armpen from runes 3) last whisper (40% pen) 4) 15 armpen from runes + last whisper (40% pen) 5) 15 armpen from runes + last whisper (40% pen) + full TBC (45 arm-red)

armor	dmg red		dmg from MS 71,5	41,69%		204,0816327 56,5	36,10%		223,6421725 42,9	30,02%		244,926522 33,9	25,32%		261,3890963 6,9	6,45%		327,4087933

The same with 150 extra armor

armor	dmg red		dmg from MS 221,5	68,90%		108,8646967 206,5	67,37%		114,1924959 132,9	57,06%		150,2790897 123,9	55,34%		156,3197856 96,9	49,21%		177,7552057

What do all these numbers tell us? If your opponent has a lot of armor you need armpen to even do SOME damage. If he has only a little armor it is evel MORE worth it, because the curve is degressive.

Last Whispers gives in both excamples nearly the same absolut amount of benefit in pure damage (40 and 42). And Last Whisper itself gives 40 AD :) If you get even more armpen against a low armor enemy it gets better and better (see 5 from the no-armor calc above). It gets better like more and more armor gets less benefitial for your opponent.

Hope this was not to much text and the right wording...

Bottom line: omg, get armpen! In any case! :)
