Ok I will dare to say it
Since tha game is called The rift and rifts are the new dynamic idea, why not use them somehow as an alternative way for gearing up to T2
This way things can be a bit accessible to casuals and will also let us count the heroes that love hard dungeons
After an alternative way is established make the instances killers and hard to offer bread and butter to those who beg for challenge
And if they complain tell them to follow the alter way or shut up for good
