From what I could tell during the big Writhing Wall event last Autumn and Winter, I would think the incursions in Solstice would have permanently killed the Alikr dolmen grind.
I am not entirely certain why folks do the Alikr dolmen grind or what they are achieving by doing it, but, from what I could tell, the Solstice incursion grind that was officially part of the game back in Oct?/Nov/Dec certainly seemed to be similar but easier to do. By easier, I mean quicker, more convenient placement of camps, and also daily quest rewards for doing it.
But now that Writhing Wall is over, Solstice has calmed down, and Alikr has heated up again. Does anyone know what happened? Am I missing something vital to my understanding?
