Dude, HC is already a joke. Its an absolute farce. It has nothing to do with being difficult.
The fact that HC players can level with gray mobs completely takes out any challange.
Just walk through Durotar and watch all the level 18-20 players, pulling an entire camp of level 9 mobs...
Your contribution to this topic shows that you have never played a hc toon yourself, yet you have a very negative opinion about it. Neither hc nor non-hc players can level by killing grey mobs, most certainly not a level 20 toon killing level 8-9 mobs in durotar. Killing grey mobs grants exactly zero experience. The only reason one might do that is to farm profession items (cloths, meats etc.) or to complete grey quests because they still grant xp for 25 levels above quest level, but that will not bring you anywhere close to 60.
HC is exactly as difficult as non-hc unless your general non-hc game plan involves dying a lot for whatever reason (faster traveling in the level range 1-10 before rezz sickness is a thing comes to mind). The mobs you fight are the same, the quests you complete are the same. The most notable difference between hc and non-hc is that hc toons are ceteris paribus generally equipped with sub-par items because they cannot access the auction house to buy better gear. Albeit this only really makes a difference for gear dependent classes (most notably warriors and other melee classes) and matters to a way lesser extent for hunters and warlocks in particular.
There's plenty of players in the Still Alive guild that look down to non-hc players. The majority of guild members are 'good people', we're all here to play the game in whichever way we like to. If it's not for you, that's ok. I just don't understand the amount of vitriol non-hcs have towards hcs, especially because I can't seem to find any example of hcs feeling a comparable hate towards non-hcs.
It's a game. Get a grip mate.
