Everybody who thinks this is Okay is either a selfish BLU mage themselves or just isnt particularly interested in doing FATEs so arent bothering to care about the plight of others.

BLU is a fantastic "normal" FATE killer with its range of fun AOE's. That's fine. What ISNT fine is that a single BLU mage can just delete a boss FATE single handedly. If this was a Personal FATE that only applied to the BLU then no problem, but doing this denies the FATE contribution to everyone else in the zone.

The whole point of the FATE system is that it SCALES with players. The more players in a zone, the longer FATEs take to kill, the more health the FATE mobs have. This is an important part of the design as it lets everyone have a good chance to contribute damage even if arriving slightly late or when hundreds of players are attacking one FATE target. BLU spells with their instant kills bypass this and "steal" the FATE.

There is literally no reason that SE shouldn't disable Missiles and Tailscrew in FATES. It's two skills, it wont affect the general fun of BLU mage which is doing raids in parties of 8 BLUs and hunting spells or doing the Masquerade. BLU will still be excellent at FATEs without those two gamebreaking skills.

Noone minds that BLU can speedily do FATEs, its the fact that it denies the FATE from others in the world and encourages a community of ninja-pulling and every man for themself, which is completely contrary to the entire FATE system design.
