Being a leech is really easy actually:

1) Save up your coupons.

2) Don't fall in the temptation of getting a wide Ninja-Pool (you can't afford it). Seals only in complete Treasure (Lightning or Jinchu 1).

3) Build up power (magetamas - lucky board is your friend....for a very long time)

4) Kurenai (fully skillbroken) is free of charge...but a grind definitely worth it.

5) Most importantly: be nice to strong guys, you beg to every day. whispering "help me TI" is not a question and it just leads to you being ignored. Nobody has time for an * (and NOOOOOOOOOOOOOOOOOO doing TI 20 times a day just to be a help-train is not fun).

6) P2W players don't give a f*ck about your crying in arena and any other mode.

7) No. if you only have a third of the battle power of the avergae pool, you do not deserve a legendary gift pack.
