Research Pages Drops

[casdegere]

I am having a difficult time finding Chanter pages from mobs that are of the appropriate levels. I am up to Level 24 Spells;

Page 390 Tasarin’s Grimoire Pages 8 and 9 Velishoul’s Tome Pages 16 and 17 Velishoul’s Tome

And very soon level 29:

Pages 43 and 44 Velishoul’s Tome Pages 67 and 68 Velishoul’s Tome Pages 75 and 76 Velishoul’s Tome Pages 108 and 109 Velishoul’s Tome

However, finding mobs of similar level to the pages i need has been somewhat...difficult. Mobs that appear to be the level of say level 24 pages are dropping 16-20 pages etc. Has anyone else noticed this or maybe I am looking in the wrong places? (Which obvious I am since others have much higher skill)
