Exactly, and just like with other campaigns, when they're not on, people frequently don't want to do the related content. Incursion campaign, even the exp campaign.
I get the business angle of campaigns: get hyped, the thing you wanted is finally available but it just leaves everyone who missed out behind until SE brings it 'round again. Like Sulevia's +1 after this month, or certain trusts (like good RDMs*, Ullegore, Shantotto II,).
* They did add a tutorial-method to obtain Koru-Moru.
I'd honestly just rather the old stuff be more consistently available. For instance, make high quality augments more common, as a permanent fixture of SR. I have a few max-stat pieces, a few decent, and a few that I've never seen a good version (Witching robe, lengo pants).
