I realize this is so old but....
Giving Shal a Qor/Neg Karma only BoF spell would suddenly make a world of difference.
Purge >=< Blind
Dazzle < Blind
Then you get hold as well.
Sure they don't last as long with buffs up but a 3 school Qor should be able to log a 3 school Shal if you get off the blind or even if you eat a few arrows and get the blind off between their dazzle. If you don't and you start to take a lot of damage you just run away. If you're a Shal toon what can you do... fumble your way trying to run away? I can't run through the whole game blind anymore, I don't remember it that well anymore. Instant rescue is a bit crazy. What if Rescue was near instant but damaged you for 5-15hp?
Then again I haven't PvPed in ages and don't know what it's like now and I'm honestly not that interested in PvP at this point. Meridian59 PvE! Who would of thunk!
