Re: Vanguard... Whats up?
Check your graphics settings, i had a bug yesterday where the draw distance said it was maxed but i was surrounded by fog. set it to close and then max again fixed it.
As for mobs and quest difficulty, thats how the game is. Its goal is to force grouping, you can solo but most of the rewarding quests need a group, just like how it was with EQ. As for your agro issue, its probably the agro range on spells. This is why melee with ranged weapons are better pullers, spells generate alot more agro then arrows or daggers. Its usually best to pull with a low dmg or dot spell if your a caster. Another thing is slow spells or basically and any nondmg spell, like debuffs.
