Even intermediate EH is enough for any player, consistently, to remain below 300. Some swords may be required but Trees and Magic school is a must so you expend more BP per full sword. You don't need to aim too high up if you don't want the SR ticket either.

Just rank for ~250 and you'll have everything you need.

Also depends on which event is currently being held because if the UR or RR is wanted for any reason by the majority of the community, people will be ham-slapping each other for rank 300 and below.

For example, if Nubee chooses to release a broken card for RR that gives Lilim's buff as an AOE instead of single target, and can be awakened, you're going to have the hardest time ever reaching 300 because everyone will be fighting for 2 copies of the card.

Sometimes the efficiency will depend solely on how many swords you have to burn in the EH.
