Personal opinion: Juggernaut gives you versatility, but less of a dps ofc Mara is all about that heavy dps that all raiders love, but he's melee so it might be on a disadvantage sometimes

Well, from personal experience and from post i usually read, Juggernaut is not far behind in DPS from a Marauder if specc correctly. So there you have it, you can choose a Tank / DPS class (Juggernaut) or a full DPS class (Marauder) that doesn't go to much far ahead from the other, but it can't tank. Juggy's tanking is also a new experience if you tanked as a Powertech. They can take a larger beating, but have a struggle keeping multiple mobs in aggro. Your choice really. A really well played Marauder can actually top any class Dps, but they are rare

I'm having the exactly same problem with my juggernaut! Does anyone have any feedback on this? Please!
