It's a big issue in PvP. It even happens in Ranked Feast! People will enter with 'technically' ilvl150 but they'll have really lots of pre-level 60 gear and in PvP it's a huge deal because a teammate with gear like that results in a sure loss unless the other teammates are gods.



If it's frustrating in PvE, imagine how frustrating it is in Ranked PvP! They'll die at a drop of a hat and can't output any heals/dps.
