Honestly 1 of each role is enough. No need to have 2 off all roles. In regular content 1 of each is more then enough. Elite is a different story most run two healers or 2 tanks depending on the situation. If one troll puts out debuffs and the other gives power and Shield I feel that's not needed. One troll can do all of those things. Now if you had one regular troll and 1 buff troll that would be different. Even with healing you can say one power gives HOT and the other gives Burst heals. Yes that might be helpful but every healer power is capable of healing solo. And only time to run two tanks if there's a boss or a game mechanic that calls for it. Like in GOMe. But that's just my opinion. Maybe you'll get a group with a weak super role and they need help but as for running 2 of each definitely not needed. Just imagine the dos will be so slow because now you have 2 dps not 5. I've pugged for every raid and never was 2 of all roles needed. Even in Source Wall when it first came out or TSD. Two of each role wasn't needed. But it all depends the Player.
