2. I'm not sure about the retainer resetting everyday. I usually don't have much of a problem with this, but I do know that you'll have to reset your retainer anytime the wards crash. This is the only explanation that I've ever heard about the issue. The more your servers ward system crashes, the more you'll have to rest your retainer. :(
3. Correct. The idea now is to kill monster as fast as possible with as little downtime as possible. The faster you kill things, the more sp you'll get. :) Feel free to spam your strongest attack!
