Living story and level
Not at all, you can join the LS at pretty much any level.
Actually many steps of the LS was good for leveling.
(and the other 8 elite specs maxed too)
this depends highly on the living story.
The origin of madness (4,5 weeks ago) was in a level 25-40 map. so you needed to be bout level 30-35 to participate.
The edge of the mists (2,5 weeks ago) and now escape fromLion’s arch are both in a map where you are upgraded to level 80. So in theory you can do everything.
The issue with upgraded to level 80, doesnt mean that you really are level 80. You don’t have access to exotic/ascended stats, you dont have all your skills unlocked and you dont have all your traitpoints. So you are still somewhat dissabled.
For this current living story this means that you can easily follow the zerg (big group of players often leaded by commander) and get most things done. Some achievements in the living story are a bit more concentrated around soloplay (like finding 30 pieces of rubble) and you can have more issues then.
But because off the fact that one of the daily achievement (today it is to kill 10 off scarlets toxic alliance members) you can still get the meta achievement and the bulk of the achievement points. (and you can get the higher level things, but it is slightly harder).
Joining a guild and asking some of your guildies to party up with you, helps a lot as well.
Arise, opressed of Tyria!
Well, you can do the LS at almost any level, it doesn’t mean that you’ll be effective at any level.
Last LS a level 15 could join the Marionette, get achieves there but you would be a dead weight most of the time.
