mo1 failed because of bugs, cheats, server instability, and poor game design. not because of toxic veterans or players. if you believe that then you really are stupid.
people who quit because they got killed werent going to play the game for long anyway, and making a more protected game with less potential to be killed will only go further to drive the game away from a hardcore aspect. some of the sand, like walls ,needs to be taken away in a large amount to fix things such as locking a main city in. that i will agree with.
but i also feel like walls shouldnt litter the map either to block people from interacting with you, hostile or friendly.
