Makes sense to add an easy mode.
For those players that are truely casual players.
They typically dont have uber loot no greensteel items, no named gear.
Perhaps even the Permadeath groups.
I give credit to the ones that can play permadeath toons and stick to the values of you only use what you find in quests, these players restrict themselves from buying and selling at the AH, don't accept gifts, only transfers within the chest are acceptable. Can never get past part 4 of the shroud so no tier 3 crafting. Most don't have opposing elemental weapons or the power 5 weapons. so it is a much more challenging to run quests when you do not have the tools to face difficult and high HP/Dr opponents.
I am too foolhardy a player and often challenge beyond my capabilities. Death is a close personal friend and I visit him far too often ;D.
