I like the buff nerfs u done with eu, but IMO balance could be only achived if cleric/bard were completely removed along with all the buffs and passives from the other masteries.
Then adding an extra mastery where everyone could find buffs (with proper requirement of stats set and mastery levels), so they could not ignore pulling it up.
This way bless spell and ulti screen would not be important since they can pot their hp up, wizard and lock could get a snow shield or something like that so they dont die instantly.
But at the moment ctf will be still about poping some buffs and healing the party.
But you still have the best attempt i saw in years to balance the races at least no triple screen and permanent bless spell is available which is really a big thing for FW
