It's pay2win and it's not, at the same time.
- it is pay2win - because the items are there...
but it's actually not, because you would need a good investment to be able to effectively overpower half of server.
1xPet - 40€
Gear fortify - 35€
Gems - 35€ for 4x lvl8
Reforging - 20€
that would mean around 100€ for best pet and +15 gears and maybe good reforging, BUT you still need to farm around lvl5 gems, adornments, souljades, emblems, trinkets, oracle crystals, exalted gear, chalice, pet skills, psr's, hff's, radiance, talismans etc.
