i pwled a chanter to lv 62 and 26 aa (to max extended duation buffs) in 22 hours.(didn t know G-ends was that good).
i did a lot better with a monk.lv 62 and 36 aa (to max faster FD aa).....in 6 hours and 45 min
i had bring my monk in griegs ends when he was lv 39,XP was AWSOME.
i was pulling 15 to 20 mobs on me (shaman lv 75 14300 hp and 2450 ac raid buffed),i had my druid in zone to cast on me the damage shield (lv 72 druid)when it faded..i had 129 damage shield on me,with ds potion (they tend to sometime dispell the DS potions (sometime i need to cast from 1 to 4 on a big pull)..........
U need to cast lassitude on you and cast idol of malo(s) if u pwling a caster,or let him hit all mobs at least one damage (easy for a melee class tho)
with my monk i was able to keep all the agro with lassitude,i was even sitting sometime to let them hit me easier (with hot heal on me).epic,aa heal ect.
i can tell u at lv 39+ they(alts) getting very good xp ,around 7% per kill...x15 to 20 from a pull
PS: one or 2 times i nearly died from a big pull,but the pathing in there is not great and can let you recover pretty easy if needed
i checked your magelo and u may not be able to pull that much,but you should be able to get better xp in griegs ends than other zones from your lv 56 wizzy,because the mobs have low hp....until you hit like lv 62+........
=========================================================================================================
well it's still not that easy : you still need to cast Halcyon (our best HOT) and got it all time on you and spot heal here and there..
i had lingering sloth until my monk hitted lv 51 or so,(where i got him 30aa,at 8%or so per kill,at 100%in the aa ),,,(then i had enough ORUX,and faction to buy lassitude rank 2).
with lassitude i was able to pull more mobs on me........
OH, BTW, my monk don't have LOTD ,can't have it because he is my 8th char and all the veteran rewards already ben taken
