the TC5 research looks slightly interesting, at least you don't have to gather points anymore (I think), you just get the note and use the points attached to it
and yeah, in 1.8.9 you make chunks more polluted every time you do magic. You can clean them back up, but that requires resources
also, wands recharge from the local vis, and can drain chunks of their vis. it regenerates, but that takes time.
tc2 or 3 did the same thing, I think
