Yep, same here...well, all except the female gamer part. ;) Maybe if they take out the coin charge for gear swaps, I'd try again. But I can't afford the millions it would take to experiment, then swap back to my normal set-ups. 

That is a problem, too. I've been playing for 2 years and have a good selection of champs to choose from. But I have no interest in spending time figuring out who to put on a team and what gear they might need. If I couldn't kill it with any of the teams I put together, then it's not worth the frustration. I game to relax and have fun, not to be frustrated!

Or just wait until some youtuber find the solution? I don't think this new content was made so it can be finished in just a week or two.

The spider in FL60 is the same one that was in a lower floor (nether spider).  You may remember that you had to apply a HP BURN to get past the last bit.  It does not say it in the level 60 but you have to do the same thing, or else the spider will keep getting up on you at the end.

I am far from a fancy player, but ,my team consisted of: H Smashlord, Scyl of the Drakes, Coffin Smasher (for the Burn), and 2 Valeries (for constant shielding from poison).  My total power was 67k and total time was 21:44.  Scyl will pick up any guys that get knocked over.  Best to toggle AUTO on and off near the end to get the Burn on when you need it.  Coffin only had 50% chance of getting it to stick but it worked.
