its not, its for the hardcashers who bought 2-5k nets. just to bypass the time you need to aim for the fishes you want. harddrop nets on everything first catch =)
edit:
at a certain stage, like lvl 5-7 on all the fishes, aiming for a certain range of rarity is very time consuming. its kinda more comfortable just to drop some thousands nets on every first catch. just to hit next milestone. this in particular gets more worse with every higher tier of rarity. of course the first 5 or 15 are "lets say" easy catches. but after that its very time consuming to aim for the good pattern, to squeeze out the most per nrg aka netdrop. thanks to rarity 1 spawnings :o
