A level 25 doing a level 25 event will receive 7%. Seems pretty close in my opinion. That's about 29-30% decrease in efficiency, so if you need to go fast go for the properly leveled ones. Unless you're only planning on doing one event, in which case a 2% loss in percentage points becomes barely measurable. I'm actually surprised to see the same 10 people posting on the forums but here is my guess : You get a lvl 80 Boost for Purchasing HoT.You get a lvl 80 Boost for Purchasing PoF.1+1 = 2In theory if you own HoT+PoF you legitimately should have 2 boosts to lvl 80 so you can play 2 classes you like at the same time and work on progression on each class.As it was mentioned by someone above, lvling and that's not counting all those bound materials that don't have a price tag but that can take a while to acquire by a solo player. According to the Guilds page under gw2efficiency, the current total cost of a maxed out guild is 15,672g, 711,262 aetherium and 57,281 favor. A lot. My guild, TACO, is a small one. As other people have said if you don't want it you can just use it on an existing character who is already level 80. They'll get a full set of exotic gear with celestial stats and the Level-80 Boost Package which contains 2g, some dyes, food and 5 teleport to friend items, among other things. All of that can be kept or deleted if you don't want it. 10 reward tracks on PvP and WvW should take 1 or 2 weeks for a casual player for lvl 80. On pure PvE it depends a lot. Without abusing dungeons I would prolly take 3 or 4 weeks for lvl 80. If you can abuse dungeons, even if carried, it wouldn't take more than 2 weeks. GW2 has a fairly easy grind. I have 3 level 80s and I've used 1 out of the 3 to beat all 3 main quest lines of the game. I always use my Necromancer. The base game and the 2 expansions. Not just that I've accomplished a huge of amount of things. So getting to my point. When I go to another one of my level 80's who hasn't accomplished what my main character has. After review, crafting for about $5 gets the character to max in a reported roughly 2 hours. Bear in my mind, the $5 is based off gw2crafts.net. The 2 hours is from player reports. Most how to level fast videos suggest about 25 hours or so. The difference between 2 hours and 25 hours is worth $5. I could find no better way. this isn't just due to high level players, its also because of repeated nerfs to central tyria because in their testing arenanet decided newer players couldn't handle the difficulty of things like "skills" and "water". this isn't sarcasm, they literally tested the game on a group of inexperienced players and determined they just couldn't handle the difficulty of the leveling zones. BvF2s.
