1. Paladin has divine might but rangers have know the angels from harper enhancement tree which adds half your int mod to damage and tactics.
2. Self healing in ddo is hardly a problem anymore with epic destinies. Also a ranger gets cure light/moderate/serious wounds from ranger spells.
They also get freedom of movement...
3. Paladin get light damage core but rangers get a lot sneack attack dice from deepwood stalker.
Rangers also get the following...
Fortification bypass : 10(Advanced Sneak Attack) + 10 (Mark of the Hunted) + 25%(Mark of the Hunted) = 45% more than paladins.
Doublestrike : Dervish (25%) offhand + 10% offhand (whirlwind) + 5% mainhand (whirlwind) = 40% - 10 % zeal paladin spell = 30% more than paladins.
Oh yea paladins will loose on exalted smite/divine sacrifice if they choose to take killer from deepwood stalker. While rangers keep exposing strike.
So another +20% doublestrike for a total of 30% + 20 % = 50 % more than pali
+5 Incorporeality (stacking) (whirlwind) + deflect arrows every 2 sec.
Oh, yes especially this too. For rangers off hand weapons are affected by +1 critical threat range (Advanced Sneak Attack) and +1 critical multiplier (Deflect Arrows) which translates to ~ 26 % dps .
I dare you show me what makes paladin top dog with all these things taken into consideration.
