I have been waiting to find another chance to get this for a long time.
I understand people being defensive of rewards for stomaching previous iterations of PVP but I could see people like myself who hated the previous system really going for it if it means getting those rewards again.
Now that queue times and playing pvp isn't a slog it just makes sense imo.
To add to this, I don't think people realize just how much incentive the crystal system really gives me as a potential pvp player. I've never hit PVP as hard as I have this mode and partially it's because inbetween the big rewards I can use the crystals on more glam options, AND I'm getting wolf marks at the same time.
Most of the time my FC used PVP/Frontlines just to help level alts, now it's a game mode with a "track" to go on that includes glams/frames/etc. This adds the tail to the mode that it needed to stay alive because I can clearly see what my next milestone is and the matches are fast to get into and usually fast to get out of.
I treat it like a battle equivalent to Golden Saucer where I'm hopping into a game to see if I can get to the next crystal pack to get that up res'd MCH coat or buy the allagan gear I missed.
While incentive shouldn't be the only thing that warrants people playing a game mode, given that the only "fast" way to do pvp before was Frontlines which sometimes feels like a complete slog, a fast new mode with both normal rewards and specialized rewards (marks/Crystals) portraits to show off, gear to show off, and genuinely interesting takes on the PvE Formula creates a great foundation moving forward for the mode. I just have to hope they don't leave it to die.
I'm really hoping they capitalize on this momentum and/or have "mini letters" from like the pvp dev team or with Yoshi-P to discuss direction PVP is taking and treat it like a serious mode. I know that's pie in the sky probably but as someone who's never given a single inkling of a care about pvp, I'd be super bummed if the breath of fresh air it finally got was snuffed out a few weeks later.
