Legendary Weapons - Need 1 WvW reward track completed for Gift of Battle which is approx. 8.5 hrs of gameplay in WvW (assuming no Reward Track boosts) . It's tedious, but not horrible to get. That, and it's fairly easy to get Ascended Weapons with the Elite Spec. collections, that you often don't really need Legendary Weapons for the Stat Swap. Legendary Armour is obtainable for PvE, WvW, & PvP without needing to set foot outside each of those modes, with different gates (both time and skill)PvE - Raids, requiring wing/boss completions, a collection, and cost of Materials. I think it was approx 10 weeks for your first set, and 21 weeks for ever set thereafter.PvP - PvP League Completions for Ascended & regular Shards, and cost of Materials. Low end can get 1 Legendary/season, regularly can get 2 Legendary Pieces per Season, but you can then grind for Ascended Shards to stock up for subsequent seasons. (My personal favourite way, despite the name-calling in PvP)WvW - Approx. 1 Legendary/4 Weeks of completing Skirmish Track, and cost of Materials. If you enjoy WvW, this is for you, as you get it passively just by running around whacking things. If you are just starting WvW, Completed Wood Division in prior week, and your server has the lowest war score, it works out to approx. 4.3 hrs of gameplay in WvW per day to max out your Skirmish track. On average, you're looking at about 3 hrs/day, less if you manage to get Outnumbered for a long while. (WvW takes a while though as it's not the most material lucrative method). WvW=fancy name for pvp, I'll never set foot on any pvp map, since 2020 is the year to ditch pvp luckly I've found a new game 100% pvp free not even duel is avaiable.
