I completely agree. It was a shock the first time I met up with a golem years ago in game on my caster and nothing worked I had prepared. Instead I had to beat it down with a quaterstaff that took forever and about 100 cure pots. It taught me to be prepared next time.
The changes made that remove this kind of difficulty was a bad move by turbine. The same thing with making things like blindness and curse on a timer. These should be perminant until you drink a pot, have a spell cast on you, or shrine.
I see so many who only carry one weapon, no healing pots, no cure / resist pots. The changes made ot the game didn't make it easier. It taught players instead to be lazy and steam roll through quests with MOAR DPS!!!
