Thank's for this but i'm not sure this is gonna be enough.
Example: I encountered rare foe with 6!! arch mods in a level 77 delve, it was impossible to avoid, can't run out. solution : die or altf4 well...
Do you really think that this is the kind of foe we should encounter on this low tier stuffs.. this kind of rare should only appears on "high end" tier content. (or if it choosen)
Maybe doing something like that could be good.
-white content : 1-3 maximum arch mods
-yellow content : 2-4 maximum arch mods
-red content : could be max i guess
I also think that you really should play your game few days before releasing a new content. this could avoid a lot of simple mistakes.
I cannot believe that this content has been tested and if it's the case the testers was hardly drunk.
Hope you'll change guys.
