Frontlines are just fine, no need for any changes.

It's popular in Japan but dead in NA/EU.

Not necessarily popular, but: It's not dead. But that's similar to how Japan has a over three times the raiding success and likely population as NA/EU despite offering the exact same rewards. Different culture and all that.

The core of the issue is hard to nail, though, because PvP as such is far from unpopular - League of Legends is probably still the biggest game on the market and counter strike and DotA2 are popular as well. Which is why I tend to go broken record mode when it comes to rewards - they're not the issue.
The primary issue is: People in this game don't enjoy the PvP offered in this game. Why? Gods know.
It probably isn't repetition.
Part of it might be the community, but LoL has been notorious for that as well and it didn't kill the game.
Might be a bad fit between the community and the content - FFXIV isn't exactly catering to the high competitive type.
Might be the gameplay - The trinity was not made with PvP in mind.
Might be the fact that newbies play with veterans due to a lack of MMR - especially in frontlines where 8-man premades are possible.
Might be queue times, but even when queues are swift as when Feast got introduced, it always dies.

Have you given PvP a try?
If not, why?
If yes, do you still play occasionally?

There have been a few threads on this in the past. It generally comes down to people not appreciating the attitudes of PvPers.

Frontlines is boring. Its basically head smashing against other players with little to no tactic involved other than, run away and let other team bash their heads, grab bases, attack nodes that pop around the same times every game, and thats it. They should've made Sieze like an actual SIEGE mode so we'd be defending actual areas like castles with walls and crystals on the inside, nodes that don't require everyone to smack their heads against as they pop up all over the map (looking at you Shatter you POS) and grants the team points they can use to obtain upgrades like monsters and summons that defend the bases or something.

Frontline slaughter and Secure USED to be fun, until they removed the assist node spawns that would buff teams depending on their damage output. It added more tactics and thinking in the whole battle, but apparently thats bad because now its all redundant and boring. Grats on Shatter, it still sucks, and Feast can go starve. -_-

Couldnt be more far from the truth, it just that majority of players dont know how to play these modes properly. Now if you could do Shatter as an alliance premade vs 2 other GC's being also premades it would reveal real meta behind this mode(in 72 there would be multiple 4man "blackops" teams scattered around map securing/camping small ices for example), lastnight i witnessed how Immortal(dunno if it was premade or not)literally owned both Mael and Adders strategy vise, they literally abused our push against adders and flanked them and as soon as we managed to get adders base they retreated to kill big ice leaving us fighting useless fight with respawning adders.

So for those immortal players i must say "GG well played and keep it up!"

Snips

Your aware that all it takes is Maelstrom to be angry at Flames to just constantly harass their team making Black Ops groups somewhat useless? If Mael and Adders weren't busy duking it out they'd realize, oh right, THAT mechanic. Yeah no, the mode is plain as the Sieze.

Again its not really modes fault if peoples are stupid and i agree it sucks when it happens, this is the reason why i personally prefer 24mans instead 72 as there are less derps there to screw things over.

I've tried PVP on a few occasions. The old level 30 Wolve's Den once for the PVP participation trophy, Secure out of curiosity back in the day (but not Slaughter), Seal Rock (curiosity again), 8 man Feast when it was released to try to get a Fenrir Pup, and Frontline Roulette (mostly Shatter matches) to farm Wolf Marks for stuff like minions and Orchestrion Rolls.

I haven't played since getting the rewards I was interested in this patch. I'm not a very competitive person.
Shatter is probably my favourite PVP mode for the same reason a lot of PVPers hate it-I can contribute a lot to my team's points without engaging other players

Feast in particular also had players with very bad attitudes. I was playing in the unrated mode during preseason and I was still seeing abuse directed towards players for poor performance, especially healers.

Yes, I did PVP enough to get a book I wanted for glamour purposes a while back.
No, I stopped participating when I achieved my goal above.
12 year old attitudes: Ain't nobody got time for that.

Have you given PvP a try?
If not, why?

No.

No, because:

1. MMO PVP is always horribly unbalanced. Either because of overpowered healers (healing in PVP should DELAY death not PREVENT it, big difference) where no one ever dies, overpowered DPS that can burst someone down instantly and it becomes that OP class 2-3 shotting people, or drastic gear imbalance where whoever has the best gear always wins even if you're better than the other person. I honestly prefer PVP where everyone is given the exact same stats and abilities and it's on you to use them to maximum effectiveness. But I've always maintained the first and only ever truly balanced PVP was Pong.

2. The attitude of PVPers has often been really awful, competitive gameplay really brings out the worst in people, sore losers and sore winners especially are the worst types of people to interact with. I notice a certain element of people tend to be attracted to that mentality and they generally infest games with PVP.
