If you like challenges, lvl up the elementalist yourself and use the booster on Rev. If you don't like wasting time and don't mind grinding the rev to 80 then boost the ele. With that being said, I have yet to lvl up my ele to 80 and my rev is still sitting at lvl 2. All the information above I've gathered from talking with people and looking The XP is wasted until you do the first instance of either Heart of Thorns or Path of Fire to unlock the Mastery system. Don't freak out about wasting this XP, though. The total amount of XP required for Masteries isn't that huge anyway. Masteries are a long-term project to get them all, and XP isn't the only limiting factor. Go pick up another class, and start doing the MSQ. When you hit the level 70 MSQs, continue on SAM from there. The MSQ will give you ALL the XP you need, to hit 80 on your first job. Fun fact, if you started at level 1, and just followed the MSQ from level 1, it'd also carry you to 80, while also feeding you gear. IMO it's a lot more fun to do map completion at max level with all 3 traits and all utilities unlocked. So players can boost to 80 and then start doing map completion, and get all the things mentioned above, including keys for doing map complete. The Hero points they earn will work them towards unlocking an elite spec at that point. It doesn't give you the gear and stuff the xpac ones do but still boosts you to 80 if I remember correctly. It has the additional items (gear, dyes, bags), they're the same boosts. Only difference is the bought boost requires you to have an empty shared slot rather than just giving you one additional free slot for it. For your first character, play to level 80, then buy a DLC package. Even if the DLC package has a level boost, use that level boost on your second character. As you are leveling up to 80, check out the gem store. If you think you need more bank or inventory slots pay for the quality of life features. It's advisable to have at least one lvl 80 levelled the normal way because it helps learnt the game better. A lot of people boost, go straight to level 80 areas in HoT or PoF and then find themselves unable to do anything having skipped so much of end areas of the core maps (Orr) and Living World Season 2 Something that has bothered me for a long time now, this all stems from an accident of placing a valuable infusion into one of the level 80 boost gear that was "given" to my character (the infusion was a+5/+9 agony infusion into one of the "given" exotic earrings). Make a new character, use the boost, delete the character, hence and repeat. Use it. A level 80 character using it will get all the equipment, bags, etc. Then delete the crap you don't want. However, some classes get full exotic Celestial gear, which isn't a bad alternate set to keep. A few days i was in exactly your position. I played a thief and was around level 30. i decided to buy the first 2 expansions for 30€. First of all you unlock mounts, you need a level 80 player to carry you through the mission that unlocks them, but being able to ride on a dinosaur makes exploring really easy and cool. S7vr8D.
