not that bad at all. i bought 2 ql 100ish towers to put around the guild controller for only 75k-ish.
the top towers, ql 250 cost like 20 mil a pop, so good luck getting those (and the skill requirements too...)
now the new yalms, paint, and mantas ? thats another story. i hope you got deep pockets and uncle pennybags as your best friend cuz i know i cant afford 10 mil for paint.
