How much leveling content do the two expansion packs bring to the table?

[Ghamarro]

Especially when compared to the amount of leveling content the pure vanilla EQ1 has which, atleast to my understanding, is quite little? Atleast in terms of quests etc.? My plan is to level a Halfling Druid and a Dwarf Paladin, but it just struck me that I'm probably going to have my hands full leveling even just one character, so maybe I should save the other one for the expansions, so I don't miss out on the leveling content provided in those? What do you guys think? Is it worth waiting out with the other char or should I just level them concurrently right now in vanilla? I personally value the leveling process as just as important a part of an MMO adventure as the end game, so I'm kinda itching to see it all.
