Though not exactly the right place... 5D and jD lost all invuln, 2D (non OD) has increased start up but keeps foot invuln, 4D and 6D lost head attribute invuln (still body Invuln). 5D, 6D, and jD are actually slightly faster (in exchange for that Invuln), and j4D just doesn't hit low now.
Anywho. Lag is just annoying in general, but we all know this ya :B
