I've been a WoW player since early BC. Been a guild leader for 95% of that time. When WoD came out, my fianceé and I decided, for the first time in 7 years, that we weren't going to be GMs anymore and find a guild that meets our (high) standards.
Our biggest holdup, in the few guilds we've trialed with, has always been the use of potions by members of the raid. I don't know if I'm just being an elitist A-hole, but to me, why would anyone not want to use 2 free 25-second buffs to their primary stat for any given fight? I want to play with players that have the mindset to do everything possible to increase their character's performance, and consumables are on top of that list.
The most common reason (or excuse) I've heard for why some people don't is because "its farm content, and I don't care about ranking" or "a potion isn't going to make or break the fight".
Personally, for DPS to not double pot every encounter is unacceptable and lazy. I've even gone as far as saying that tanks and healers should at least pre-pot, too. All healers, imo, should pre-pot intellect, then you have the option later to use another intellect pot if you need burst healing, or use a mana pot if you're running low. The main tank who starts the encounter should pre-pot armor, and the offtank could pre-pot agility/strength, depending on the class, then you have a 2nd armor potion later to use as a spare cooldown. I tested an armor potion out on my undergeared DK tank, and it was roughly a 10% physical damage reduction, and 2000 attack power. Hardly anything to scoff at.
Am I being too picky to find a guild that enforces maximum potion use?
