A message from a solo player that is currently doing Angels of Death difficulty

Hi Saber interactive 
I have just read some part of your "message to the community questions on steam" and I have some input I would like to share of my own.
Now in your update to the community you mentioned about the games difficulty being too hard, well from my stand point I think thats the purpose of a higher difficulty, Veteran is hard sure but it doesn't compare to the Angels of death difficulty (far from it actually) but I will say this, in some of the problems facing solo players right now is like you say due to how passive the friendly AI bots are and i Agree with this statement, I personally think that two of one outcomes happen and i can even mention a bug with them too.
The first thing i noticed about the AI is that when reviving the downed solo player the other AI bot just idles there not providing any sort of support in keeping the tyrannids off of the other AI bot reviving you. 
The second thing i noticed is that the AI friendly Bots seem to fight just like the Cadians because they only seem to want to fight the smaller sized tyrannids than to actually focus on whats doing damage on the player the most, so I would like a change to be added that allows your friendly space marine AI bots to also be a little more aggressive against Large tyrannid forms but only excude from the boss fights themselves as they are do able as a solo, some boss fight arenas a little more buggy than others "cough carnifex fight" plus the only way they can help in the boss fight arenas is if they enact as a distraction for the solo player to be able to heal themsevles without watching the stimpack they just used go back down to the same sized health bar they where at prior to using the stim pack (or worse0 i still have painful memories of the rippers area where your AI bots won't attack the Neurothorpse's until everything is dead which is really painful as this gives the rippers time to rip you to shreds.
As for the Bug i have experienced with the Space marine Bots is that in the first Carnifex Boss fight you are in a church themed room before the carnifex forces open the the door infront of you to enter the room, now for this fight i would like to say that just fighting the carnifex alone had a weird bug where if you dodged the unparryable attacks the carnifex does ive noticed that it can still damage the player (for some reason it has a bigger AOE when it does these attacks than the ZoanThorpe boss fight, make that make sense to me?) but this part of me explaining where the AI bots come into this well let me tell you because it is also a bug affecting the player too. 
In the Carnifex boss fight the items in the room are a little buggy ive noticed that you can still get caught in these items even when they have been dismantled by the player or the carnifex, which has also added to a collision Bug where when the player is downed during this fight the AI bots bug out and refuse to acknowledge that the player is downed, i have a feeling that these invisible collisions not only hinder the players movement in the boss fight (as I know as I died so many god damn times to being stuck on an invisible collision and that cost me the boss fight on many occasions) but also hinders the AI's ability to heal the player during this fight, its a little weird but i can say that this fight with the carnifex was no joke, how I managed to beat it is just impressive to be sure. 
But its a fact that items with a hidden collision is having a negative effect in the boss fights so i recommend a short fix to remove some items in these arenas and when the fix is applied to remove the hidden collisions to then re-add these removed items from these fights.
The Angel of Death difficulty is no joke when it comes to playing the campaign but i wouldn't say its impossible to do im already dealing with the thousand sons introduction into the game and will let the community know how i get on from there.  (if anything the operations diffuclties are more harder than the difficulties for the campaign is) 
But yeah I feel the difficulties themeselves are do able, just some solo players just need to keep fighting and endure these painful deaths before seeing the truth in completing each difficult level. 
(Also a side note: when ever you do the Quick shot thing I swear you can do this without holding the right mouse button as ive noticed that in most cases just holding down the left mouse button works better than holding right mouse button and then pressing left mouse button, just a food for fought on the quick shot action there).
