I've been slowly chipping away at the Carina's Vol.3 Challenges and have come here today to reflect on the worst I've felt since Abyss of Legends first (and only) run.
@Lagacy 's challenges were a great appetizer to Vol.3. Not hard, gave you an excuse to use a bench warmer (5* Stark Spidey), and feel the power of a max rank ascended great 5* champ. The challenges themselves were a fun walk down memory lane, and at the end you get a great set of rewards for your time. A+
@Karatemike415 's challenges at first glance looked absolutely horrible. The Avengers that you had to use for the challenge weren't champs people would commonly take to R4/R5 and sig 200 so I felt pretty crappy about using resources on taking up Black Widow and Thor to R4 (already had a 7* R1 Hawkeye, 7* R2 Iron Man, and kept 6* Ant Man at R3). I started out the challenge pretty salty with what needed to be done, and kind of salty at Karate Mike for the "garbage challenge, but as I went through the quest I found myself having a surprising amount of fun using these OG champs at their highest potential. By the end of the Avengers Challenge I did a complete 180 like the crowd at the end of Rocky 4 cheering for Rocky instead of Drago!!! Great job Mike on a perfect balance of difficulty, fun and nostalgia. It does suck that I'll likely never use my BW or Thor again so putting resources into them kind of sucks, but at Valiant those resources do come very quickly so not a total loss. A-
Karate Mike's Zemo challenge I went into intrigued because of the stacking Zemo synergy, and I already had an R5 sig 200 Zemo from last year (and I LOVE Zemo). Going through the whole quest for a second time was annoying, and I wish there was a different quest he could have used, but in the end I had as much fun with this challenge as I did with the Avengers one.

Now...... good lord.... Yesterday I decided to jump in Fintech's challenge (I'm not tagging him because my feedback isn't very positive, and no need to shove it in his face directly). Holy good lord did I NOT enjoy a single moment of that challenge. I took my 6* Mojo to R4 sig 200 which didn't feel great because I'm not the biggest Mojo fan and the 7* exists but figure R4 would be the min. requirement to make this not a complete massacre. I solo'd Hercules, and Nick Fury on the path pretty easily, Havok took a couple revives to get the rhythm down and AI to cooperate with throwing specials, but noting crazy... Every other fight though was just a rage quit, phone throwing, slobber knocker...

Top of the stealers of happiness are Warlock and MODOK... Watching both of these fights just demolish my revives, health potions, patience, happiness and sanity had me questioning the meaning of life and our existence in this Universe (not really, but it did make me question why I'm wasting my life playing this game FR

). By the end of the path, after beating Dragon Man, I felt no joy, I felt no satisfaction, I felt no Eagle Powers, I just felt anger, frustration, confusion and a full bladder (I downed several beers to help me get through the trying times that took hold of me).
I sat there realizing that I hadn't felt this way since the revive vacuum of Abyss of Legends years ago, and remembering thinking after my completion run that I'll NEVER go back in to do a single other path of that quest and to this day I haven't (all the Vol.2 Carrina's Abyss challenges site untouched in my list and will until the end of time). Then it hit me.... I have to go through this quest again with Tigra and Jabari, but all 17 fights with a champ that's arguably OP (in comparison to fatty McSpider legs) who has a very high skill ceiling to play properly. I've come this far, I've drank the beers, I've cried the tears, so I can't NOT do the Tigra Challenge at this point (I really want 7* Stark Spidery and Massacre), but the emotional damage the Mojo challenge gave me will scar my mind permanently.

Fintech... why don't you like joy, happiness, comradery and fun? Nothing about that Mojo challenge was remotely fun. It seemed like he thought of a sadistic way to prove he's the best player in the world, by thinking up these challenges, completing them and then presenting them to the community in a "IF YOU ARE WORTHY OF MY LOVE.... YOU WILL EARN IT BY SUFFERING AND STRYFE!!!! PEASANTS!!!!!"

TLDR: Fintech's challenge really sucked lol, F-
