Well, weather you buy it or not it is true. In my case I absolutely stuck to normal for a long time. I capped (level 10 at the time) on normal with many quests I didn't run yet. I did run normal because I was learning the game and the game was much more difficult back then (2006).
Since the games launch a truckload of buffs, changes, gear options have made the game much easier and new player friendly. This one addition of adding champs into heroics doesn't come close to canceling out the absurd levels of power characters have now versus what they had back then. So no, I don't feel this is excluding new players as much as folks would like to think it is. New players are still in a much better off position than the old timers were.
Since the old timer completionist vets first leveled up things that were added/changed to make the game easier:
- Ship Buffs (Elemental Resists are huge in lowbie land)
- Much better equipment
- A twice over revamped enhancement system (The first one had a cap of FOUR total enhancements you could have).
- Content tweaked to make things easier.
- Revamped XP
- BB
- Favor Reward system
- Dungeon Scaling
- Hirelings
- A Wealth of information via here and the wiki
- DDO Store and all that brings to the table
- Much more I am forgetting right now
Things added to the game to make a challenge:
- Champions on Hard and Elite.
Yeah, I don't feel bad. Game is still much easier now.
