Path of Exile 2 has launched into early access, and with it comes a revamped skill system. PoE 2 will stay in this early access state for about six months, but that doesn’t mean it will lack content. The early access has three full acts to enjoy, with plenty of new content coming until the official launch. Perhaps the biggest downside is that only six of the 12 classes are currently playable, many of which are the best classes from Path of Exile. However, these new classes will also trickle in over the six months.
