Once upon a time I brought up a PoV commanders on TC or Piken square really hated, even thinking of it made people either rage or say I was stupid. But tbh when you think deeper on it, thief does have some pretty serious untapped potential in WvW Zergs.
Dravvi at it again I know, well let me dive into this.
Much like soulbeast is in my not so humble opinion one of WvW's most valuable classes (to which I invite alot of them to my squads and am currently smashing desolation by doing so), I believe with the right builds and the right state of mind. Thiefs can bring some REALLY useful buffs to the party and even more? They can be devastating in Zerg fights.
Skelk venom can make a huge difference in zergs, when you apply that venom to your entire party that is a extra free heal for all 5 players over the next 5 attacks for a base of 1200 HP per attack. Might not seem like much but every bit counts.
Missing scrappers? Shadow refuge can be a major boon to everyone in your party, stealth your party for a few seconds and jump right into the middle of the fight.
Pitfall and Seal Area are two insanely good CC abilities that can be used to give the upper edge to players in zerg fights, though they take a short time to arm? if placed properly they can descimate players in choke points in a matter of seconds.
One of my favorite abilities on thief is dagger storm, it's very strong and very underused. Over dagger storm's duration those daggers flying out in every direction bounce off enemy targets and the thief evades, this can give thiefs a upper edge in zerg fights where enemies are clustered. One thief per party in a 25+ person zerg with that equipped can be a huge amount of damage in just 4 seconds.
Shadow portal can make a really good substitute for a mesmer when used properly, though only allowing 5 people. Should each thief carry one? it can help get zergs from point A to point B very quickly.
The remaining venoms can be used to boost the damage output of heavy condi reliant parties, apply them to a scourge? Watch what happens.
I tend to think outside the box when commanding, while I understand the meta has its place? I think people often understate the potential of each class and what they can bring to the table.
