25 feels too spammy for a 25 sec duration. But the main thing I don't really feel comfortable with is that it makes it too much an easy 'burst window', while I rather the class be defined to be more of a consistent one (Crater laid out the correct paradigm about how having burst is actually utility so the tank with the highest burst should have the lowest contribution).

What it currently does it give an increase that adds to that consistency (increasing blood weapon time); the main problem is it does it really badly (and really shouldn't cost resource at all currently).
