Survival mode Unit durability adjustments

[rediDieKante]

First, I have to clarify, this is not the one millionst "I can't beat Very Easy mode" discussion. I did beat Very Easy, Normal, Hard and Insane (the normal Insane, not Insane 1).

The current durability for Units in survival mode is:

• Most ground Units:
  
  • low durability (Insane 1 and up): 3
    
  • normal durability (Hard and Insane): 4
    
  • high durability (Normal): 5
    
• Crawlers:
  
  • low durability: 4
    
  • normal durability: 5
    
  • high durability: 6
    
• All arial Units:
  
  • low durability: 2
    
  • normal durability: 3
    
  • high durability: 4
    

Fangs
The increased durability for Crawlers makes a lot of sense, as the reason you buy them is literaly to get shot at and die, wich results in them getting killed often while not leveling up that much. But the same applies also to Fangs, which only have the normal ground Unit durability. Actually, compared to Fangs, Crawlers do survive more often and level up more frequently in survival mode.
There is also the (survival mode only) subsidized Crawler card, wich makes Crawler level ups free, while there is no such card for Fangs.
These reasons make Fangs the inferior Chaff in survival mode.
Fangs should get the same increased durability as Crawlers (and maybe also free level up card)

Wasps
While many enemy unit composition heve insufficient anti air against Units like Wraiths, Overlords and, to some degree, Phoenixes, you will, at least in higher difficulties (Insane) encounter Mustangs nearly every round, often a lot of them. They are often the only Unit capable of shooting at air targets. While Amor Platting/Field Maintenance Wraiths or Overlords are immune to Mustangs, and Phoenixes can stay out of range as long as other Units are in front of them, Wasps will get hard countered nearly every round.
This is why I think Wasps should get the normal ground Unit durability instead of the arial Unit one, as of rigth now, they are not worth it in survival mode.

Tl;dr: Increase durability of Fangs and Wasps in survival mode.
