They should make jump/ledges work like GW2. If you jump is high enough to visually get over an object, you can do it. If there's a ledge, doesn't matter where it is you can fall off of it. If you survive just depends on how high it is

Played beta all day yesterday and have to say it was a blast ^^ I know the dev's are playing other mmo's in admission by Yoshi as part of making XIV so I hope they get some great aspects from all games out there.
