Diversity is good .. or atleast not bad. I for one, have gone with the flow. I have all the mods installed. Or at least all the ones I need. UP for flying on the dogfight servers, HSFX for SEOWs... etc. And about every clean official version of the game as backup.
I really don't understand the "mods kill/divide the community" accusation. People have always been divided across X number of servers (having different difficulty settings etc. attracting certain people and making others go to other servers). Now that the X number of servers use Y number of mods(again, attracting certain people and making others go to other servers) the people are still divided across X number of servers. Those that don't want to use mods, can still find plenty of non-modded servers. I visit them myself from time to time.
As for OP's first post: Have been trying to make time to test DayZ. Sounds like a great mod
