There were different methods to powerlevel (PL) throughout EQOA’s lifespan. The most used technique was to take a healer and run them through a group of low mobs while having a ticking-heal on their character.
Eventually the BPoA was introduced, making PLing a breeze.
Other techniques included pet-PLing (fixed), having a higher level kill the mob after its health is at halfway, and outside-the-group healing.
The unfortunate part of PLing? Tanks and healers trying to level became almost useless. Meanwhile, petters, casters, and alchemists became incredibly popular.
