Our company procedure changed from the “Evacuate Left/Right/Front/Rear/All” to simply Evacuate.
The onus is on the cabin crew to determine if it is safe to evacuate from a particular door due to terrain (think 747 with no nose gear, tail in the air the 5L/R slide would be near vertical), fire, obstructions etc.
The moment you say “Evac…..” too late, those that understand the word who are compos mentis sitting at the overwing exits will be halfway out the door before you say L or R.
