Yeah, Ikr... It doesn't give you the damage bonus or heals you like a full fragment will, so it's just entirely useless compared to the other 2 talents. I mean it could be a really good talent if you at least could get a minor damage buff and didn't require you to run a marathon to pick them up, as you said. DBlades is somewhat rng too, it's just less shit than DA and doesn't require you to move.
I guess my gripe is that those 3 talents aren't really all that comparable in terms of dps or utility. Like it feels they shouldn't be on the same tier. Maybe it is just my extreme dislike of that tier that's talking but yeah...
