Just to clarify: Personally, I don’t have a problem with PI (or any other external buff for that matter) in general.
I am just trying to be practical.
Does it feel nice when you can contribute something unique in a group setting and does it make you feel special? Yes, I think so.
Is it enjoyable to listen to your Teammates constantly bicker about Power Infusion, to have people whisper you that they want Power Infusion, to have people in a Mythic+ Key type that they want to have Power Infusion every 30 seconds, to have people whisper you after you have finished an encounter, telling you that you used Power Infusion on the wrong player, and that they would have been “the best target” for it?
What if, it doesn’t even matter, and even if you didn’t use Power Infusion at all, you would have still finished the encounter succesfully?
Well, I for one don’t enjoy it. If you do enjoy it, and I don’t enjoy it, well then who’s to say which one of us is right?
There are numerous other abilities, that also make a class or spec feel unique and special. Just to name a few from the top of my head:
Mass Dispel. Spell Reflection. Spellsteal. Mind Control. Ring of Peace. Death Grip. Gorefiend’s Grasp. Leap of Faith. Demonic Gateway, Stampeding Roar and Wind Rush Totem. Innervate, Mana Tide Totem and Symbol of Hope. Pain Suppression, Guardian Spirit, Ironbark, Blessing of Sacrifice, Blessing of Protection Life Cocoon, Spirit Link Totem. Divine Hymn. Force of Nature, Earth Elemental. Divine Shield with the Final Stand Talent. Anti-Magic Shell and Cloak of Shadows. Enrage Purges, Magic Purges, Disease, Poison, Curse, Magic Dispels.
I don’t know about you, but when I use Mass Dispel to remove 7 Stacks of Bursting or use a Lifegrip to save someone on the Sire Denathrius March, it feels just as good to me as giving someone Power Infusion.
So the options are to remove this one spell from the game, or expecting all those envious people you talk about to grow up. I’m not saying you are wrong, I don’t even disagree with you. I’m being practical. And one of these 2 options is clearly a lot easier to implement than the other.
And just in case anyone comes up with the smart suggestion to just “play with other people”, “just play a different game” or that this is just “part of an RPG”: That argument can also be used both ways: If you want external Buffs to be such an integral part of the game, why don’t you just play another game? WoW Classic has Power Infusion as well, and a myriad of other Buffs like Retribution Aura on top of that, with even more being added in Wrath of the Lich King Classic.
