There are some of us (actually really just the minority of the turtle HC player base), who had the idea that we don't want to lose our HC status so we stay at lv59 to do dungeons or even raids. The problem is that if we wish to remain HC it means we cannot get the level 60 rewards if we choose to level on slow & steady and we cannot get level 60 gear for the raids.

My suggestion is that upon reaching level 60 HC players are not immortal automatically, but to get the reward from HC they have to ask the NPC at the starting zone that you wish to be immortal, because you finished the challenge. After getting the HC rewards the HC mode should never be allowed to be turned on again.

With this there could be lv60 players doing dungeons/raids as HC and they will still have the chance to get level60 gear and the rewards from leveling.
