Trying to make a build
From what the wiki says, sigils of the same type share CD timers. You might want to shift over to two different types of sigils. Either a stacking and a proc on crit or perhaps a more permanent thing, like Accuracy or force with one of the proc-ing sigils.
I tried vuln and might on crit thinking I could give myself a power boost with my FT, but I didn’t see as drastic a change in damage as I thought I would. Dunno if that’s because FT just wasn’t hitting the targets correctly (possible, but I saw damage and plenty of crits at 39% crit chance) or the sigils were actually sharing a cooldown.
Whatever you do, don’t use the target dummies across the land to test your theories. They are damage-able items, which you can’t crit on.
I haven’t totally tested the theory of sigil cooldown sharing, but I do trust the wiki. If you want your own testing grab a sigil of might and earth and test them out on the golems in the Mists.
— On the WvW/PvE idea —
WvW and PvE are . . . different monsters. WvW includes PvP elements, and you will be severely disappointed when you find that the build you owned a monster with didn’t even faze an enemy player.
Loudmouth, lousy PvPer, and mediocre PvEer.
I don’t own, I just play
