My issue I've had with the level editor as of late is the lack of triggers that are not character/player specific.
For example, I am trying to make a class map, where each class has different amounts of health, speed, etc, but I cannot do this because there are no triggers that would allow this to happen.
Change hitpoints of all characters in region 'A' to value 'B' (WoAhZ's idea)
Change speed of all characters in region 'A' to value 'B' (not sure if this is already in)
Change armor type of all characters in region 'A' to value 'B'
Change nickname of all characters- This could go on for quite a while.
My suggestion is for every Character trigger in the level editor (or at least most), having a generic 'all characters in region' version would be extremely helpful.
I'm suggesting this actually for PB2, but I'm not sure if PB2 will be worked on anymore.
