DD is good but does too much and doesn't make it harder.
Resilient dragons gives dragons more health, making it longer and more epic fighting.... reduces damage NPC's do to dragons.. meaning no longer will a farmer/mudcrab/bear/wolf manage to kil la dragon.
plus DD is alot more buggy and problematic and i don't like some of the "added" extras in DD
Ehhh, you do realize that not only does DD give Dragons higher health, but it actually gives them better Resists and an Armor Rating too. Higher end Dragons have 500+ Armor, almost Armor Capped. Dragons get new Shouts too, and new Breath types for various Dragons. Alduin has around 8,000 Health, is Armor Capped, has good Resists, regens health slowly, and can not only use his usual shouts + Unrelenting Force and Disarm, but also MARKED FOR DEATH! By and far, DD makes Dragons much stronger and tougher than Resilient Dragons does.
Here's a Lvl 50 Nord Paladin with a pretty good build and a follower along with Odahviing taking 23+ minutes to kill a Blood Dragon and a new "Wyrm".

The guy lists his char's description in the Info, and even with 70% Resist Magic, you can see the Steam Breath just devour his health. The Frost Breath doesn't hurt him much though, since he does have 70% Resist Magic and 50% Resist Frost.
