I agree with OP. I am asking for buffs all the time. There is no reason to be asking for them in shroud, people know the quest, they know what is needed in there to make it go smooth;y. They should know that an 11 minute clickie (pretty much the most duration your going to get out of a non stoneskin clickie) will just not do it...not in part 1, not in part 4, not in part 5. The point of buffs in the shroud is pretty simple...you can recharge your mana before jumping forward, so no reason not to buff. In regular quests maybe a little less. In reaver no excuse not to buff. Zero reason whatsoever, the charge is childs play to get and you can jump out for mana.
I am seeing not just a decline in buffage out there but a real and serious decline in quality of arcane play. No CC comes up all the time, no wands for extra damage in part five (clearly since why would the arcanes want to use any plat , and the wizards who do not stock the debuffs for part five. It is the barbarian mentality of kill count with people thinking that arcanes are only nukers...if played that way they are hardly worth having in your party especially in raids or elite content.
