Can future PvP let below max level to take part like PotD to help leveling?

I don't know why people are so obsessed with being against PvP providing PvE benefits.

Well, that is easy to clear up: PvE benefits might lure people into PvP that are not interested in PvP and people do not want people in PvP that have no interest in PvP. That has two reasons:
1) People who have no interest in PvP typically won't try to get better at it, so they will never become gosus you can have serious competitive matches with.
2) People who have no interest in PvP might simply AFK to grab a quick losers award.

The latter is common when the reward is exclusive to PvP, because even people who absolutely loathe PvP feel the need to get in, whereas if it's not exclusive, those people got other options. The prior isn't really an issue as such - if these people are amongst themselves, no harm done. Players who take PvP serious however have quite an issue playing with these people.
