I remember starting to play warlock because my friend old me "they could summon everyone else to themselves". I thought that would be anytime, anywhere, including in combat and not recquiring assistance. Also I remember my friend telling me he would boost me in instances and I asked him "wtf does boosting in instances mean" and he said something similar to "we go to caves, I kill monsters and it rains xp". I thought xp would drop from caves like minerals or something and I had to pick it up.
