People can get near full ilvl 90 without stepping foot in Titan HM. With the Echo buff, assuming the entire group isn't new in a Duty Roulette, it will be almost too easy of a kill. I, personally, just did a full Duty Finder relic run queueing solo as a SMN and didn't have many issues so I assume the community is getting used to the fights as a whole. The added bonus of new players being grouped with veterans doing their daily DR runs leads me to believe there won't be any problems with new players getting along.
