I mean yea you have people that love the healing class as a general concept. A holy centric magician that can utilize the power of light to slay the enemies and rejuvenate the health of allies.
People do love to play healer but truthfully nobody wants to be a full on healer as it's boring and quite frankly just not fun. It's the same situation with Tanks if all you are is just a meat shield then you may as well be a puppet with 2 buttons.
This whole closed minded notion that "Healers only heal" and "Tanks stop doing damage leave it to DPS" is just absurd. Everybody is equal and important to the task at hand in some way shape or form and not everyone has to be one trick ponies when they dont have to.
With Shadowbringers coming up, I couldnt be more excited, but the White Mage changes are just especially heinous. The fact of the matter is you are removing OPTIONS in combat which is something you should never do regardless of the state of the game.
How do you go from a game like Final Fantasy XI where you had spells as far as the eye can see on top of the spells you obtain from your sub class usually black magic or scholar if you were a wiz kid, to now where the healer ONLY heals.
XI- Cure I II III IV V Protect Shell Blink Stoneskin Aquaveil all the Bar and En elemental buff spells Banish I II III IV V Holy Dia Diaga Diaga II Sneak Invisible Deoderize
And so many others
XIV- Protect.....Cure I, II, III, Holy....yea that's about it.
And now were getting protect removed in favor of Dia which was always traditionally a lvl 1 spell now it's a max lvl spell explain that one to me.
Bottom line- nobody likes it when they have options taken away from them. Why do you think people enjoyed classic Wow so much? Because classes back then didnt limit you in silly ways you could make yourself whatever you wanted to back them and have skills/spells up the wazoo.
