1. 'Duping system' is referring to "Hidden Potential System" (Use identical cards to unlock more stats in this system). This is for when you reach rank 50, which if you're addicted you've probably already reached. Search "Hidden Potential System" on here and it will give you the whole enchilada. KEY POINTS: This will be relevant once you read up a little more from the article here. A) Must be IDENTICAL CARDS for this system, NOT like SA raising (aka un-dokkaned version of a card cannot be used for a dokkaned version's duping system) B) Feeding (as in training) a card with one path unlocked to another (otherwise identical) card with a DIFFERENT path unlocked, WILL NOT give you both paths unlocked on one character ONLY the SA stat. C) Orbs are scarce, I wouldn't use up all my orbs on every single UR unless you deem the card absolutely necessary, or otherwise couldn't do missions/events.

2. "This card" can be unlocked aaaallllll the way to a "LR" card. This is particularly important for F2P (free to play) players since, as implied, this card can be attained with relative certainty if you grind (spam play levels for medals/zeni/whatever you need) diligently.

3. You guessed it, grinding is part of the game, it is literally unavoidable if you want to be decent, not even good mind you.

4. Right again, SOME events are especially time-sensitive, some will last a good chunk of time and then disappear for an equally/longer amount of time. It is important to ration your time to doing things that will actually benefit you instead of just grinding out everything.
