You might want to save the quest reward for Charr in the Catacombs until you're ready to hit level 20. Then you can level up by accepting the reward from Rurik. Depending on disconnects, I think it might not be difficult to finish the title with fewer deaths than my LDoA:
Finishing LDoA definitely takes some determination, but keep at it and you'll get there eventually.
For ranger, if you don't already have it, you might consider getting the Game of the Year upgrade, which gives you access to a /bonus max damage bow. The Nevermore Flatbow is awesome in pre once you can meet the req.
As others have said, saving the quest rewards for level 19 will save you some time spent deathleveling. My $0.02: a high level ranger in pre doesn't really need a secondary.
