Bug- Unable to cast heals/buffs while targeting

Draxys

I have only experienced this with buffs, and guildmates tell me heals also have this problem. When targeting an enemy, I have to look at the sky or the freaking dirt to cast a buff. It's just a slight annoyance in questing PvE. However, this is a much bigger issue than it seems, because what happens when I get around to doing dungeons, or trials? If I'm a tank and I have to take my focus away from the boss and look at the ceiling to cast a buff or something, that could quickly go wrong, especially in trials. Please address this.
