What's this about a 'crimson day'? Is that like the Christmas event but for Valentines Day?
Yes.
Completed the Whisper Catalyst today (whisper quest/singe now rotates on Tuesdays with the weekly reset). Crafted about 50 blast furnace's during the last week hoping for an ok-ish one with rampage, got none - that sucked.
If you think you have the patience for it try being a Sherpa, I'm sure a lot of them started out the same way, completing their goals then decided to carry new players.
I've been farming my catalyst too. I'm at 42% right now. As for crafting, I've probably crafted at least a dozen Hammerheads. I've gotten only one with Feeding Frenzy and Rampage. Unfortunately, my masterwork is handling which is next to useless. I have tried ones with dynamic sway control and other shit I feel is virtually useless on PC at least. I have been much luckier on the Blast Furnace. I have one with Kill Clip and Outlaw, which I like for PvP and another one with Rampage and Zen Moment. Not great, but at least I have Rampage. I think I've made about 10 of those. The handcannon I've got has quickdraw and shield disruption which I actually like as a supplemental tool. It's a good weapon in general even if it has shit perks.
As for raiding, I've just started doing it more or less. I've gotten the first boss down in the Last Wish Raid and almost got the second down.
