I am friendly to new players and I don't mind helping out newbies with advice but I simply do not understand how people screw up common sense/basic/simple mechanics.
Example 1: Death Knights
You must have a level 55 to even create one. Is it 58 or 55? regardless..
IT GIVES YOU GEAR FROM THE STARTING QUESTS.. IT GEARS YOU..
So why in the living hell do people put random weird gear on their DKs as soon as they leave Eastern Plaguelands. You know what I'm talking about.. the DKs with Int/Sta or Agi/Sta gear. Or even the really odd ones who have random +38 resist Heads or stats that make no sense to wear.
So taken from that example and grouping with many other people and classes who do something similar. Are the primary stats for classes that seriously complicated to understand?
Example 2: AOE AOE AOE
Bigger than #1, I simply can not begin to comprehend that how STANDING IN FIRE MIGHT SEEM LIKE A GOOD IDEA..
Either people just refuse to download or know what DBM is, they lack the ability to pay attention and press their abilities at the same time or a combination. I'm not fully sure but the number of people after 7 years of this game who still stand and die in AoE is mindblowing. Luckily the AoE isn't enough to kill you in LFR Finder, only enough to piss off your healers.
Get DBM! Stay out of bad stuff, win the game!
Example 3: Class Mechanics
"Hey Warlock, DI me"
"Huh? What's that?"
JFKLDSJORIEJOWEJOIFJEWOFJ AHHHH!!!!! That's just one example but the amount of people who get to 85 and don't know their spells is growing rapidly.
Is it because leveling is so easy people don't have to learn the basic and core abilities of their class? Your class trainer gives you all of your abilities, and the tooltip even goes into depth about what it does, what its purpose is.
Perhaps I expect too much out of human civilization as a whole. I'm usually a calm person and my days of screaming at idiots for dying to stupid simple mechanics are past me but they're starting to come back I feel. When I heal BGs, people LoS me trying to chase someone down, when I do dungeons you get two types of people from my experience. There's the full decked BoA elitist who needs to post his recount of low level content or there's the newb prot warrior in cloth gear (yes.. it has happened.. more than once)
Oh and speaking of Plate wearers in cloth gear.. I DO NOT CARE IF ITS BOA IT IS NOT OK TO WEAR CLOTH BOA AS A WARRIOR!
