Actually in lowered tiered warring kingdoms the use of SW and ET is very good.. Especially when your opponent hybrid only logs in twice a day to attack/op... it's not very effective against super active hybrids though... but if you have a halfer rogue who only logs in twice a day to do NS runs, ET is a great way to drop that built up stealth.. And same goes for all those elf/mystics in the ghettos who are playing pur? mage and only log in twice a day to do their ops... A few SW ops from your pure attackers will save alot of damage on your own kingdom from spells... Not good for super active kingdoms but works great against liw tiered casual kingdoms..
