Bard nerf is good

[Nubrication]

Ok, which winrates are we talking about here? You wanna reward skilled play when BRD cropped above 50 in higher tiers for being too powerful, was that because people couldn't LoS?.

If you don't know how LoS works and positioning yourself then you clearly don't deserve to be anywhere near Crystal tier. That's the thing, FFXIV PVP got nerfed so hard that even bad players with no "REAL" skill, no awareness can make it to crystal simply by playing one class really well. In feast we had to know how every single class worked, so most of us played every single class to know the minor caveats and things to look out for when playing against said class. Also what winrates? I'm talking about the nerfs: BRDs got punished for playing their class really well whereas melee basically got rewarded for 0 situational awareness.

Also regarding the "synergy" argument, you must lose your mind looking at the reaper kit. "Just how am I supposed to play this?! Is Arcane Crest for offensive or defense, I don't know!"

RPR HAS SYNERGY, it's entire burst relies on death warrant. Here's a free simple tip for you:
1. Cast death warrant.
2. Cast 8-stack Plentiful Harvest
3. Oh no he, guarded!
4. Cast LB
5. Cast Communio
6. Oh look that tank is dead.

Crazy right? It's almost like RPR toolkit works in synergy.

Should I use Arcane Crest for offensive or defensive? Who the heck uses it for defensive unless you are stopping a crystal push and need to buy time.

All jokes aside: you clearly don't play BRD and you seem to have some vendetta against them because you probably main a melee class. But if you play ALL THE CLASSES without bias, you'll notice that BRD nerf wasn't even necessary.
The only time BRD used to be able to score kills was with silence burst and that's ONLY IF YOUR TEAM knows how to focus down 1 enemy in higher tier games. Because really good healers are a thing. People that peel for and shield teammates are a thing.
In perspective: I play RDM, SCH, AST, BLM, MNK, BRD, PLD, DRK mostly when climbing. BUT I ALSO know how to AND play every class in casual.
