Increasing the difficulty on Ragnarok mode

[Corrndog]

I totally agree that Ragnarok mode is not challenging anymore. I don't understand why few people thinks differently.  

Improve ideas:

• More bosses/gods, becouse of the title and meaning (We've actually two meanings of Ragnarok:  Fate of the Gods and Twilight of the Gods.) 
  
• The Ragnarok course (15 waves based on mythology)
  
• Maps avaible only for Ragnarok (Asgard,Midgard,Bifrost etc - Harder to cade or with special abilities like burning bridge in case of Bifrost)
  
• More bots ablities (For example first wave could cause snowfall which would slow down movement,attacking,shooting and healing. It also fits to mythology - Blizzars and frosts will come first, Fenrir [if add] could jump over the cades etc)
  
• Special shrine/replace existing (Recalls special monster/god/boss. Maybe team would need make offering, something like lootable sheep/relict or sacrifice)
  
• Bots shieldwall
  

I wouldn't want bots to be able to avoid projectilles, kinda annynoing for me. It would also decrease effectiveness of range heroes which makes run longer. We've to find the golden mean between time and difficulty.
