For the most part, the new map is ok. Few things I would change but the biggest one would be the double hits on waves 6&7. I'm sure alot of people agree.
I just ran Hell before writing this to make sure it wasn't a one time occurrence. It was worse this time. On wave 7, the boss hit me with double hit 10 times in a row. 10 TIMES IN A ROW until I was forced to use a revive. That's over 19k a turn for 10 turns. With 2 full heals, a 5 turn staller and almost 70k hp, I couldn't survive it. I can only imagine people with less trying this map.
As stated before in another thread, double hit should mean DOUBLE HIT. Not DOUBLE HIT BUT SUDDENLY I GET STRONGER TOO! The imp DH= 24k+ while the summoner's DH= 19k+, both with a 7500 base attack. That isn't double attack.
The relentless amount of double attacks isn't fair either. You need to give a compromise if it double hits so much. If it DH 3 times, it needs to doze for one, or summoner needs less hp. Throw us a bone for the beating you expect us to take.
Please consider the following changes that I've suggested. As of right now, the risk isn't worth the reward, imo.
