Why the netcode issue exists, and why it cannot be fixed.

TERA's combat model is similar and handles the dancing much better.

TERA is special because it cheats. Theoretically it's easy to hack tera due to these cheating, but the korean programers seems to have some nice correction failsafes in place to make it hard to get away with it.

Just like ARR theoretically is harder to hack, but have been plagued with hacks from day 1.

Tera actually has netcode much like a dungeon crawler. It's very elegant from what we know of it. But that's why a lot of f2p instance MMOs run so darn well.
