Bogus Journey Guide

I'm not one to normally complain about the difficulty of the game. I enjoy a challenge and view it as a reason to get better. 

But the bo katan event is wack. As a f2p player, slaving away to get the requirements done, finally completing them, attempting the first tier, and getting stomped. 

Some defining features here. I have not neglected mods, I have some decent ones, but reroll attempts are stupidly expensive, and micro attenuators are ridiculously hard to come by. So I've gotten a few sets as high in speed and other stats as I can. But even those aren't near good enough to consistently beat these tiers. 

I managed to snake out a win on tier one after putting my very best mods on kel, but it took easily 2 dozen attempts. Paz was easier but still took my best mods, and then tier three has stumped me entirely. I've looked at tutorials, Ive attempted to get my characters to the required stats, but with my limited resources it's not happening. I can't get one character to the required speed with my fastest mods, let alone 2.

All I'm wondering is why ever other journey guide is a challenge but doable, but recently the journeys have been extremely hard, requiring even more unwanted investment from f2p players. I don't have the time or crystals to constantly be rerolling mods, and I should be at least given a chance after slaving for the requirements.

Anyways. Rant over.
