GW2 Gold players won't affect your character's stats or anything.
To receive all the weapons, mini pets, and other more useful rewards, Gw2 gold can play through all the campaigns and get a good start on it. But to finish it off, and this is the one part I don't like: you will need to do a lot of grinding. To finish off your weapons and armors you will need to grind materials and gold.For titles you would need to grind areas for reputation points and consumable items. It is really the only time you will come across the need to grind in Guild Wars, and sadly it is very boring. To get a completely full hall in order to receive the extra titles, you will need a lot of time on your hands. In the end though, you decide if a full hall means you will receive all the useable rewards, or if you must have the extra titles, that are only used for bragging rights. So don't worry if you can't get those extra titles, GW2 Gold players won't affect your character's stats or anything.
