Of the 3 elite specs, Willbender wow-ed me the least, and I played it least of all. I expected the new Guardian spec to be more pvp-oriented, and it does seem to be fairly well suited for that (concept wise at least, I'll leave the functionality up to people who spend more time in pvp/wvw). The rest however seems wholly uninspired. The offhand sword is a blatant copy of Revenant, and although the idea of physical skills on Guardian sounds interesting, the skills themselves are... just not.
On to actually playing Willbender itself.
It's... a mess. It's supposed to be dynamic, fluent, mobile, but with pretty much every mobility ability comes an animation lock which makes everything you do feel sluggish and frustrating.
When looking at straight-up golem performance, damage might be "alright" (honestly, it doesn't need more if it's meant to be a pvp/wvw spec like Spellbreaker), but the way to achieve it is not interesting in any way. Just spamming f1 off cooldown to upkeep the buffs (even with the reduced duration) makes this a poor mans dragonhunter. Its redeeming factor should be that it's a "fun" spec in PvE, but with all its flaws, it's not. And I can't even imagine how bad it might feel when playing in a competitive environment.
