Dazzle Doesn't Overwrite Mesmerize? A Bug?

[GnomeCaptain]

Hello,

If I cast Paralyzing Earth (PE) on an NPC under the effect of Root, the PE overwrites the Root. PE is the level 49 version of Root, a level 8 spell.

Recently I've noticed that Dazzle doesn't work on NPCs that are under the effect of Mesmerize.

This strikes me as odd because Dazzle is the level 49 version of Mesmerize, a level 4 spell.

Seems a bug.

Is this a bug?


Thanks
