you can only level up from killing npcs and wearing, using what ever drops from npcs
you can't do quests at all
if you do a dungeon it can't be through dungeon finder you need 4 people your level like vanilla
and you can't accept the quests from inside the dungeon and have to pass on any loot that is blue or epic
you can only use to the max of greens(that is the blizz minimin for being able to stay alive)..if it drops from an npc..
which means npcs rarely drop gear at all so you're likely to be naked most of the time
and this way is a lot slower due to no quests

RELIVE THAT FEELING of loging into runescape for the very first time
i used to hate doing quests so i leveled up from 1-67 from killing npcs or doing dungeons(also nps essentially since there was no dungeon quests inside in the past)
