You mean, similar to (back when the game was live) when Dark Astoria was converted to an Incarnate zone and a solo path to Incarnates was introduced?
I was all for that.
I really don't like the iTrials. (Never did)
But, right after Incarnates were introduced, that was the only way for players to get anything beyond the Alpha slot.
Once the solo path was introduced, I never stepped foot in an iTrial again.
Yes, it took a lot longer to get the Incarnates slots (and salvage) on the solo path that it did in an iTrial.
That didn't stop me from soloing my Incarnate progression.
I enjoyed the solo path much more than any of the iTrials.
