OK, so I’ve read everyone’s comments and I think I should have elaborated a little. I’m not against the idea of a follower rework; a while ago I even posted a suggestion for one here:
Level 50 follower rework 2nd draft)
My concern is that it’s going to be similar to the scrolls/spellbook fiasco where it’s “follower tome” or something similar, resulting in a “now or never” situation - a mad dash to get your followers up to L50, before the update makes it stupidly expensive, and all but impossible for new-mid players.
