most important thing about your different cc spells other than cast/recast times, mana, duration etc is knowing mob resistances; what xpac era, mob type/level/innate mr resistances, etc
your weaker "fixed" duration mez's have an mr value of 0: mesmerize/mesmerization 24s, entrance 72s
stronger "up to" duration mez's have an mr value of -10: fascination 36s, glamour of kintaz 54s, and rapture 24s w/ a value of -1000
note root is just a lvl/mr check as opposed to a lvl/mr/cha and whether or not that mob is flagged immunte to stun/mez check so youll be using roots more against wyverns or giants, especially lvl 4 root for its quicker fade, or immoblize for its quicker cast/recast time when every round of attack matters
on dazzle: reason people use entrance/enthrall over dazzle is dazzle gives the same emote text as mesmerize/mesmerization "your target has been mezmerized" or w/e, as opposed to "your target has been entranced/enthralled" so you can time things more accurately on gina. great spell but I hardly ever use it because of this
also your blur and lull line are the other half of your enc's cc cabilities, understand and master each spell as well. lastly single target tash is -39mr, aoe tash is -40. you'd be surprised how often that one extra value tips the scales on the rng and resist/land formula.
