Archaic mechanics in Maple.

Single-action restrictions, with notable actions including attacking, teleporting (major killer), potting, and looting. All of these do not allow the processing of another of these actions (except themselves for attack's case), which is very bad for latency-high players. I don't see why the server can't proc all these based on time-stamps of packets.

Also, AP-reset scrolls and AP assignment... with Xenon being a slight exception.

Last but not least, ships.
