Not to be a jerk or anything, but... your post comes across as "what the hell is wrong with you guys, doing X instead of Y??" and the horrific grammar and spelling make it hard to read.
1) 4 Liches in one map is significantly harder than a lot of maps we have here in Nutaku, not everyone has Claudia (new players might have missed her event) and I'm not sure why you're bringing up Elaine.
2) Nanaly can melt black armors through sheer volume of arrows, especially if buffed by Prince and AW Spica (and maybe AW Uzume and/or Uzume's skill)
3) Sophie can tank multiple liches due to massive HP AND MR. Olivie's horrid HP means she can tank only the KotD or maybe 2 liches, not the King AND a lich, or whatever.
4) Elizabeth is actually a very good unit, especially AW vs. Undead, and if his Elizabeth is dying then he probably isn't using Lightning rods appropriately. Also, if you're criticizing the use of Nanaly why would you bring up the Bashira/Spica combo in a discussion about this map? And new players especially are VERY unlikely to have the heavy-duty nukers like Farne, Garania or Odette.
5) Chydis was a limited-time availability unit. Even people who have played for over a year may not have her, myself included. AW Iris does the job fine, especially since Nutaku doesn't have all the really tough maps that DMM Aigis has. Also, unless they lucked out and pulled Camilla or Liana, most players on Nutaku have to make do with Iris, Fedora, Robert and the Silver healers. Of those, Iris is the best burst healer.
6) Rika's event may have been missed by several players. Or they may not have leveled her yet as she is undeniably a niche unit and most people focus on Spica and Bashira, as well as Nanaly and/or Elizabeth if they have them. Either way, don't assume everyone has a currently-viable Rika ready to pop in.
7) Farne and Sophie undoubtedly make this map a heck of a lot easier. Guess what? They're both Shrine-only black units. VERY FEW people have them.
