YES.
Both to access to Sarn Arena and PVP Quests
I really enjoyed when a larger subset of players would visit Sarn Arena or join the PVP queue every other day depending on the quest
It is the only thing I enjoy really, outside of that there is no joy in my life (I tried gold, adult entertainment, food, pharmaceuticals, relationships -- nothing else does it)
If Path of Exile 2 marks the end of access to Sarn Arena I'll have to go play some other game instead, and that other game won't be as nice because I truly believe Path of Exile is paving the way ahead in the ARPG genre -- it is just lacking in keeping PVP viable, and without PVP killing endless hordes of uneven power level mobs lacks any sort of motivation, PVP is the true end game
