There's only a few specific challenges that I can't stand, but overall I'm okay with the concept.

"Kill 30 enemies while wallhanger and also while invisible" pls no

Loki (10x wall cling),  Wall Cling Mod, Akkad (big wall and easy view of the defense target), Solo.    Worst case is you just wall climb up a little bit if you start to slip.   Bring something like an ignis will more range or a catchmoon with a recharge arcane is ideal.   As stated above...there is always a way to "Cheese".   Another good way is to also use nidus on Akkad.  Just wait long enough for a big enough pool of targets to show up, larva them, and go wall cling. 

For a riven, you do not need to beat the mission in most cases...in this case it is very true.
