Damn, could have sworn I saw a 10 there. Thanks.dude its 2g XD
I managed it quite easily on my Warrior, I died a few times but usually just ran back and killed the boss/mob and moved on.
Other then last boss. I had no problems exept sometime when i was underleveled by 1-2 levels. But then again i play a mesmer. It was a really fun storyline.
I got the impression it depends alot on profession and personal story choices, even the tuning between the quest for the same story seemed off for me. For example, the latest quests for charr, engineer, iron legion, order of whisper were rediculous easy compared to earlier quest and don't even compare them to early human quest for light armor professions.
But I was able to solo everything for my specific branch up to now (I think I miss one or two quests until arah).
Owned all of it up, only hard mission was the underwater one (played my warrior). Best mission by far was The one in the awesome asura battle suit near the end with the laser and what not!
Soloed all of them, except the last of course.
Not too hard IMO, the only one that i died twice was the Sovereign Eye of Zhaitan, but once i've got his mechanics right it was really easy.
