I just re-read your previous messages, I apologize if I told you stuff you already knew. I never intend to insult someone's intelligence or assume they don't know.... so sorry, my bad.(I was actually about to delete most of it, until you replied.)
Welcome to the LotB forum, btw.
And yes, save your hearts and extra souls for the upcoming monthly sac event. They reward special stuff and have sac level achievements, that reward goodies.
We all learned from others and so we pay it forward by sharing what we learned.
The other part of the time we are trying to just figure out the new stuff.
I myself seem to always end up learning things the hard way, so I share and voice my opinions in hopes of sparing others the suffering I had to endure. (Star Wars reference: " Many Bakura's died to bring you this information".... hahaha)
I used to be a corporate trainer, so I feel the internal need to share w/ others, cuz I know how it feels when you have to figure things out alone. Example: I earned a Lilith in the LoL grind event all on MANUAL PLAY, before I read on this forum about auto-play for grinding.
I mention this to you and everyone.... cuz I know their are folks who probably think " damn that Bakura sure does type alot.... and friggin gives his opinion on everything".....
