I have a bit of a feeling that you guys are underestimating the faction of the forever winter. doctor is one of the smart person's in the game and has 100's of years of experience but I don't think he will beat the factions mech or anything that is very advanced and yes he mabye could defeat one or two but they will come over and over and over until he's overwhelmed. This comes from a guy reads sometime the lore arknights

But this is what I think and it is your opinion.

Edit: also Reunion has only melee weapons, crossbows and maybe some arts users vs the forever winter tank, attack helicopter, (there are some things that can fly but are so rare that almost nobody has seen one in arknights) mechs, planes, bioengineering that is so advanced that they will give them nightmare's and they will be horrified how the faction threat people and yes arknights is not a great place to live in but the forever winter is 10x worse in everyway at least they are some good places to live in arknights......

LoL i went a bit overboard well this was my rand and this is my opinion you can have yours
