I like the Efts reaction to approach and aggro.

The lay on the ground sunbathing....

If you run in the vicinity, they lift their heads(with their tentacle like sensors), to see where the sound is coming from.... if you keep running, they eventually aggro you and throw the big lighting blast.

SE probably got rid of that because noobs of this generation would probably complain that it is too hard for them to navigate in this world(while standing town 99% of the time anyway), similar to removal of elemental weakness and attributes.

Things are too complex for this era. *sigh*
