Guild Wars 2

edge of the mists, eternal battleground, each of the borderlands and obsidian sanctum… what are the key differences between them? i’m in need to farm a bunch of tokens for my legendaries, would be nice to know what the best one to farm them is.

I would say best place to go for you is obsidian sanctum and do jumping puzzle

All jokes aside you get em mostly from player kills and BTW no 1 farms them just enjoi wvw and you will get em

To the op. Anet has recently upped the badge drop in WvW so I don’t think it matters where you play. However, EOTM use to be the place to farm badges. As I haven’t been to EOTM since HOT came out I don’t know how it is in comparison anymore.
Sanctum is suppose to be the jumping puzzle and guild vs guild or 1 vs 1 etc.
Borderlands = Server homelands. Tends to be a little less fast paced as EBG. Still get the fights but not usually as large scale as EBG. Also it is usually a good place for small man groups to roam.
EBG= All 3 servers in 1 spot. Ends up being blob vs blob a lot. Tends to be hyper fast action.
EOTM = is basically a round robin EBG. You tend to go round and round capping endlessly with a few fights thrown in.
Hope this helped you make a choice where you farm your badges.
