It is still a form of farming when you are using multiple characters "earnings" to pad one characters "Build" The reason they keep these things bound to each character is so that in order to get "the best" stuff for one character, you need to put in the effort with that character. This keeps the characters stats and earnings balanced. FOr example, it would be very odd to see a character who has never participated in a tourney or tw etc stacked with all the top things available through participation only in tourneys or tw. A player that wants what is earned from such things should have to put in the work for each toon they wish to have those things on. It does not make sense to allow a toon who has never competed to reap the rewards specific to participation in events.
ie. It is not the developers fault if the player has more toons than they can handle
