New Character Advice?
I would recommend finishing level the engineer. Have your guild mates assist so you can do the dungeons. If the guild you belong to is not assisting then find one that you can mesh with. Some guilds only want numbers others are willing to assist with enjoying the game. But do try and reach 80. You are over halfway there.
It takes very little effort to hit 80, and when HOT comes out youll then have an easier time getting the awesome specializations unlocked (disregard ele/guard)
Might as well just get it all to 80 rather than clogging your character slots up with half done characters.
I recomend leveling that one to 80 fast and then either go through the personal story or ignore the personal story on that one and create another toon just for the personal story. The second one you can delete and recreate as wanted. The first you keep for level 80 content.
ANet may give it to you.
