The BLM is a terrible class no matter how you look at it. Outside Speedflox it's a class that is outshined by pretty much any other DPS. Low single target damage, VERY STATIC damage and what is even worse, extremely unreliable. Like 30% of your total damage depends on random procs, it's a ridiculous dumb class that is only played for the big numbers and because people feel cool spamming flare, but efficiently speaking, it's absolute trash tier. Even if they buff it a bit it will prob still be terrible.
