From Guild Wars Wiki
Normal mode is the default mode of play for Guild Wars. It was dubbed "normal mode" with the installment of hard mode in the April 19th, 2007 update. Normal mode is the regular gameplay mode of the game with NPCs' levels being progressively raised from beginning to end.
Limitations in normal mode
In comparison to hard mode, aside from weaker NPCs, the rewards for completing missions are lower. Likewise, some titles, or just certain ranks in titles, are unobtainable in normal mode.
- Sunspear, Asura, Deldrimor, Ebon Vanguard, and Norn ranks can only be obtained up to rank eight.
- Vanquisher and Guardian titles cannot be obtained; as such, neither can Legendary Vanquisher nor Legendary Guardian.
- You can only gain 335 points, or rank 2, in Master of the North.
