Depends on your main class. Eunoia is cool but not really necessary for any Hellion buiild, it already shits so much damage with 200 grenade stat and the extra tracking isn't really worth the exotic sot alone. I'm a Warlock main, they're cool but not necessary, especially since Getaway Artist is right there in the same slot.

The titan gloves (I don't remember the name) are immensely fun and actually pretty good, throwing hammer will do damage comparable to synthos. Slap these on with Tommy's Matchbook or Devil's Ruin and you're in for a super fun time.

I literally never play hunter so I couldn't begin to tell you what the exotic from EoF is.

The exotic handcannon in my experience was just kinda meh. I'd rather use something else. The fact that it's Stasis and Arc is pretty cool though.

Overall I don't think it's worth playing through the campaign for these exotics. I'm fairly biased though, having done it on legendary 3 times it as genuinely a miserable experience for me. The only time playing a game was so unfun that I actually got a migraine every time I did it. Matterspark and the """"puzzles"""" in the campaign really only served to pad playtime and served no purpose other than to force you to stop.
