Need help rerolling
You are a twit lol. You wanted to play a Warrior since headstart but you almost maxed out a Guardian instead. That’s funny.
Soulbound stuff is lost if you intend to delete the character (which would be stupid…), salvage it if you can.
Gifts of Exploration are account bound not soul bound so you can still use them on other toons.
Well, I wouldn’t salvage all the gear on your Guardian, just in case you want to come back to him. As for rerolling, if you want to level your warrior ASAP (and have a few golds), I suggest you take a look here :

If you’re going to salvage all your guardian’s gear, you may as well just delete him — but that would be nuts considering how much time you put in. Just keep your guardian as is and either “retire” him from active play (who knows, you may decide to pull him out of retirement at some point), or use him exclusively for PvP going forward. If nothing else, he’s good to go for WvW.
Start your warrior as a different race, and then enjoy a new class, a new region and a new racial storyline.
