I use to add some lag for who is not IMMORTAL.
This is because some players to avoid the lag by spells (such as sanctuary) or skills lag, normally reconnect.

I think i've found the solution

in descriptor.cpp

in short descriptor_data::check_playing( const string & name, bool kick )
after
         connected = cstate;
         check_auth_state( ch ); /* Link dead support -- Rantic */
         show_status( ch );
i added
	 if (ch->level < LEVEL_IMMORTAL)	/* lag for mortals on reconnect C */
	 {	
		  ch->WAIT_STATE( 50 );
	 }

and in short descriptor_data::check_reconnect( const string & name, bool fConn )
after

        connected = CON_PLAYING;
        check_auth_state( ch ); /* Link dead support -- Rantic */
        show_status( ch );
i added
  	if (ch->level < LEVEL_IMMORTAL)   /* lag for mortals on reconnect C */
	{
		  ch->WAIT_STATE( 50 );
	 }

That's a solution. A better one would be to make the lag associated with spells and other intended sources be tied to the character based on time, rather than to the descriptor which gets reset when you reconnect.

The whole "wait state" system is rather brain dead, IMHO. Has anyone considered rewriting it to use cooldowns?

I have, but never got around to it.

That seems extraordinarily cruel to do. A wait state of 50 is pretty long, probably long enough that they could just disconnect and wait for auto-quit and have that be faster than dealing with a delay factor of 50. Plus there's no way to know if they link dropped on purpose. I can't count the number of times I've hit the wrong X on something while multitasking.
