You do have a valid point about the bloodlust weapons being a weapon people temporarily switch to. I do this too in WvW. At the moment, infusions don’t really do much other than provide at maximum of 5 points of stats. Which is not that significant. It’s like having 1 extra permanent bloodlust or something.
Thinking through this. Let’s say for instance, I finally got a bloodlust infusion with a sigil of battle. The advantage I’ll be given is that I will still use a sigil of battle plus that I will actually earn a stack from killing. That would be a possible advantage for this in consideration.
I’m rather undecided about this. It seems somewhat “overpowered” but it also makes sense.
Edit: Considering WvW players have a bloodlust from high rank in wvw. I’d say I would agree to a certain degree. If I’ve considered more different aspects that I might not thought of. I would be more inclined to fully agree.
