Have you started on your epic quest?
http://riftinator.com/maps-zones/epic-story-quest/ That will keep you busy.
This is definitely a bad time of the year for MMOs. We had to do a major recruiting binge to fill in for people who are on vacation/away. We can still only get 20 together for gsb only once a week, maybe twice if lucky. Still haven't set foot in RoS and only tried the 10mans a couple times.
I'm sad about the t2 nerf but with all the people complaining about it on the forums I have a feeling Trion will come out with some t2.5 or t3 5man dungeons at some point. I do enjoy the 5man dungeons more than anything since raids can get a bit stressful. I still need a few tank weapon drops from DSM and need more inscribed stones for my tank essences from raid rifts so there is still plenty for me to do.
Since there is nothing left for me to get in 5mans for my dps slots I'm finally getting the tanking role down with my rogue and it's damn fun. With 51rs/8bd/7rng I got 11k hp, 164 toughness and 18% dodge with recent Shambler Skin Tunic from gsb and purple shoulders from RD. I could get 12khp if I swapped bladedancer soul with bard but you give up too much in defense. Once I get those essence slots upgraded to purples I should be pushing 11.3k and 10% parry and 20% dodge.
Anyway, I'm hoping the EQ2 dev influence continues with more side quests. That's what this game really needs in addition to more 5mans. In EQ2 some of the quest lines are insanely long but very fun.
