I mean, the question that you're really getting at is whether WAR needed a damage buff at all. It didn't really. It needs its gameplay buffed.
This just about getting more people to play WAR again. But to do so, you have to make the job itself a lot more interesting. The single biggest mistake made with WAR was
4.2, in that they removed the gauge costs when IR was active. Instead of spending your downtime
setting up for and carefully planning your entry into your big burst phase, you spend your downtime
waiting around for your big burst phase. 10 seconds of intense activity followed by 80 seconds of waiting around. This is a band-aid solution to a deeper problem. Big numbers are exciting, but only when you earn them.
