Conditions are a complete waste for WvW. Don't bother with them, in several instances they actually hurt you more than they would help.
You NEED a ranged weapon. Don't depend on others to bring one. It's absolutely critical that you bring a ranged weapon, especially as a warrior. Anyone that says "oh you don't need a ranged weapon" is absolutely nothing but a detriment to their team.
LB is a good choice for the aoe potential it has when you are laying siege to something. The high arc can actually be hugely beneficial in wvw, where in pve it can cause problems.
Melee options are axe/mace/great sword/hammer. That all depends on how you play. Do you play with a regular group? Do they need someone to provide CC (though why they would ask you to do it when if they did the cc you could burn the enemy down faster than almost any other profession is beyond me)?
If you are going damage, go with burst. Drawn out fights in WvW are a waste. Unless you are off looking for 1v1s (again not really helping your team, there are professions much better at supply caps) burst damage will be more beneficial to your team. (example: the ability for me to reach a siege and destroy it before the enemy can react). Not only that, consider that every person you burst from 100-0 quickly enough gives your team a bigger advantage.
Ever see someone hop/get pulled/fall from the walls and run back in? Yeah that's one more defend YOU could have killed.
Anyone that disagrees, go right ahead. Give your reasoning and I will not only provide my argument, but plenty of examples for everything I've put here.
Oh and you posted this in the PvE section, so try reposting in PvP section.
