Don't worry. Healers get shunned and hated in every Game even if you are good. In ESO literally EVERYBODY hates Healers. No matter if pve or pvp. ESO DPS players also dare to say that Healer is the EASIEST role in PVE. All that while completely ignoring that many Healers have to Heal in PLATE ARMOR (less mana regen and abandoning other bonuses for healing) to be able to tank the Adds/Bosses while they have to resurrect the Tank and DPS that failed to play the mechanic or took a vacation in a void zone.
In WoW Healers get hate too (and constant, weekly nerfs) Some people scream for the same treatment that FFXIV's pvp got. Outright removing Healers and deny support players to participate.
FFXIV is the worst offender though.. its the only Game i know that outright removed Healers from a Game mode.
That said, Healers are shunned everywhere these days.
