For the same reason that a feoh wizard with 80K M.attk will do far less damage than a yul archer with 40k P.attk. You're comparing apples to oranges. Don't compared P.attk and M.attk they don't equate the same.
Well thx for reply, but I just pointed at the fact that Soulless and Reaper do lot different dmg with the same skills.. Soulless and its skills is affected by Pattack and Reaper with Mattack. I was just wondering why its so much less dmg and if its ok.. it doesent matter in the end case everyone is using wynn summons now.. but thx one more time

The (P.atk + P.skill power) does greater damage than the ((M.atk)^1/2 * M.skillpower) in this matchup. There is a bug (or feature) that has been present in the Korean Test Server, the Korean Live servers, the Russian Test Server, the Russian Live servers, the European Test Server, The European Live Servers, and the North American Live Servers.
The Soulless/Queen/Seraphim all do ~30% more damage than they should on both skills and normal attacks on both PCs and NPCs. The only saving grace for the Spectral Lord/King/Merrow is that their attack speed is large enough to allow them to do more DPS despite doing lower damage with roughly the same P.attk and skill power (when comparing the single target skills since they have the exact same skill power).
