I'm a Lil slow. We hang out in the spirit bloom room instead of the old platforms? I need more clear instructions.
You know when the Templar summons his legion? Hide in the spirit bloom room tell they leave. Then after you beat the 3 phases with those light pillars and get the check point. Everyone suicides and restarts at the top.
Where you all start before jumping down to the Templar platform at the beginning.
Have someone jump down and go to the back left area to kill the Oracle that spawns there.
Everyone else can snipe the rest of the oracles from up there.
For the Templar boss fight have everyone in the same area, but someone needs to go down and pick up the relic and shoot the shield. He/she will also help kill the oracles that spawn during the boss fight(the back left one the most). You must kill the oracles or its all over.
Hope I explained that well enough. It's late and my brain is sleepy.
Btw make sure to take out the hobgoblins that snipe you from the platforms outside the boss area.
