Galactic challenges are a pile of hot garbage

I don't even understand why it's a 3 day event. What's there to do for 3 days? Current GC only has 2 feats that are achievable by most people, the other half of the feats is basically a paywall. I completed the T5 battle with the "other" 2 feats, but will be getting a T3 crate - whoopsy-doo. Bring on some useless gear-junk, which I already have 100s of, can't f*cking wait (but I'll have to, for 3 days).

Some great content that is, complete one battle at the highest tier possible and f*ck off - that's 10 minutes of "content" at best. Honestly don't understand what I'm supposed to do for 3 days there?

EDIT: Ok, I have to make something clear. I'm not saying it's bad because it takes 3 days. Some people need / benefit from extra time, that's fine. I made the post above while still being 'mad', and it shows. My point that the length of the event should correlate with its content. I.e., the longer it takes, the more stuff to do should be there. Take GA, TW, TB - all multi-day events, all with something to do every day.

I'm saying that the whole implementation of the event is extremely lazy and unimaginative, there's no real "content" in the event, other from the slightly off-vanilla battles with increasing difficulty per tier. It's boring, dull and the only differentiating feature of the event, the "feats", have been hidden behind silly paywalls for over a month now, resulting in many people receiving greatly underwhelming rewards. There's just nothing to look forward to with GCs.
