In the leadup to patch 0.2.0, Grinding Gear Games announced an upcoming change to towers, the second biggest change yet to the endgame juicing system.
"In Path of Exile 2's 0.2.0 update, we're making it so that Towers can spawn with mechanics, including bosses! Towers will also be able to have content added by tablets from other Towers, so you'll be able to juice your Towers as much as your maps!"
The one bigger change Towers received was earlier, when the Alpine Ridge, Bluff, Mesa and Sinking Spire layouts were added to the existing Lost Towers layout.
With its narrow pathways, maze-like layout, poor visibility and projectile-blocking barriers, the Lost Towers layout is by far the worst layout, so this early change was nearly universally seen as an improvement.
The 0.2.0 change is more controversial, with some players seeing it as an improvement and others as making towers worse. Whilst the author is in the former category, I'll present both sides fairly and let you make up your own mind.
