1. Anyone know how high Storm Rider's have the Fast Cast attribute?

I ask because I just ran into a situation where I aggro'ed 1 storm rider and had backfire cast on me in like 1 second - it felt like it wast instant backfire. I was watching their bar and the backfire image came up and I straight away had backfire cast on me... This happened on and off.. ie some would cast really fast, while others were close to 3 seconds cast.
Either some of them have very high Fast Cast.. or I was lagging and never realized it... but Backfire is a 3 second cast spell.. but SR are mesmer's.. so with high FC they could easily get it off in ~1.5-1.8 seconds...
2. Just when does backfire activate?
i had a repeating situation which really puzzled me.. I was taking damage from backfire when I felt I shouldn't have.. lemmie explain.
I spotted a SR, ran up and atatcked it and then cast Fireball at it. I went through the cast timer and animation.. the spell went off and just as the spell struck the WR I got zapped with backfire.. and then took 56 damage from it.. even though I was already halfway through a wand atatck animation..
Which to me says I was either lagged (I wasn't experiencing any other lag effect's and wasn't even rubberbanding..) or backfire still effects you as long as their is a spell animation/effect still being played out. Because this happened a few times where I'd cast a spell with no backfire, start a wand attack animation as the previous spell struck.. get zapped with backfire and take damage from the spell I'd just casted..
3. Why does ANet hate players playing elementalist's with henchies? LOL
Seriously.. it's actually quitre funny.. going through Pockmark Flats with my elementalist.. 90% of the critter's there are Wind Rider's... which of course makes me useless once they cast backfire on me.. technically I could use condition removal.. but what if the elementalist isn't E/Mo? My only condition removal is via my monk secondary... and Alesia doesn't have condition removal.. so anyone trying to play Elementalist there without condition removal is either useless or has to take damage casting spells and hope that Alesia can heal them fast enough... and don't forget that at that stage (unless they have been run places) the only condition removal spell they will have by then has a 20 second recast.. so chances are they'll be backfired again and again before they can recast condition removal..
but what makes me laugh is when I went through as my W/Mo.. I saw way more stone elemental's than WR's... and of course stone elemental's are more problematic for warrior since they like to blind.. which makes a warrior uselesss... and once again Alesia doesn't have condition removal.. which means I'd again have to draw on my Monk secondary to remove blindness...
But blindness didn't really bother me that much.. however being backfired basically every single fight.. which would force me to bring condition removal.. heck I've tried that and just had backfire cast on me right away.. and then have to wait 20 seconds to recast it... just to have the next wind rider recast backfire on me yet again.. pfft!
Ah wells.. saved me energy tho.. heh. But damn it took ages to kill those group's of wind riders when I basically could only attack with my wand.. pfft!
Ahem.. but this is all of a sidetrack.. my real isse is with point's 1 & 2.. I'd love to know if anyone knows how high Wind Rider's have their Fast Cast attribute.. and just when does backfire actually activate?
edit - I know I have mixed the names up. my apologies ;/
