Buying Tackle points seems like a cheat way to unlock everything? Especially if you plan on unlocking everything for multiplayer tournaments to gain an advantage? Maybe it would be okay for single player only. Just my thought.
I think they'll add this feature. I figure that is already planned since we only get tackle points when we level up.
I'm ok with the idea of a buying Tp option as long as we only get Tp. This way nothing is locked behind a pay wall.
