Just join a group for TX rifts in a rifting community (rather than public games, which are often a mess). At some point you're going to get it. Almost all classes have extremely fast TX builds when well-geared, and if you have only 1 or 2 people in your group that have enough DPS to clear a TX in 2 minutes, all you need is a good open map (Desolate Sands is by far the best) and it'll be no problem at all.
