Using that booster for a second toon after leveling the first is really giid, though. The booster does provide valkyrie gear for thief and rabid gear for necro. The other 7 classes get soldier's gear. Also, be aware the difficulty level jumps significantly going from core Tyria to either HoT or PoF. The wiki has a good article on CC's and using them to break defiance bars. Having that down will help immensely in both expansions and the living world maps. For example, on my warrior I normally run 5 CC skills - bulls charge and headbutt, mace 3 (pommel bash), shield 4 (shield bash), and the mace berserk skill skullgrinder. With those 5 I can normally drop the break bar on even champions, unless there is a zerg that has scaled it up too high. I am going to level a toon up, just not sure which one. My two mains, ranger and ele, will level normally since I'm liking the gameplay of both. I was considering a new character just to get the mount unlocked, but I don't want to waste a boost on one I'll never play, so I'm still considering. I thought about trying a thief, they have an interesting skill set.
