I will say just because one has a class at 60 does not mean the person knows how to play the class, i have a scholar at 50 and really do not know what i am doing for the most part.
Just to clear the whole you don't have a class at 60 , that portion is nonsense, lol.
Topic on hand, when doing solo content or even dungeons as Bard with another dps it does not seem bad, but go as 2 Bards for the new dungeons or heck even multiple Bards in the Primals.. yeah it is then evident
Dps is soo utterly slow with multiple Bards in a group, and currently at 59 i really have been struggling trying to cap it, just does not feel good playing it anymore. Also comes case in point mana or Tp has not been a issue either thus far so i can foresee more and more groups possibly limiting the amount of Bards that join (Party Finder). It is rather sad. However, and maybe some of you have not read or heard that SE will be making changes.
