Crystal Conflict is a very fun mode, but theres a few things that i believe could be polished to make it a better experience. I don't play much frontline so im just going to give opinions regarding CC, but youre welcome to bring up suggestions for frontline too

- Targetting
FFXIV's tab targetting system is fine for PvE content (mostly) but it's not that great in the faster PvP mode. There should be an option (either built into the base targetting system OR as a new pvp action) that targets the enemy within range with the lowest HP. Also an option to target a marked enemy automatically. Either of these changes would make it a lot easier to actually focus on people, especially for ranged classes.

- Limit Break Cues
Limit breaks, from party members or from enemies, have absolutely no visual or audio indicators. You only really know if someone else used an LB if you've been staring at their LB bars on the party lists. This is all kinds of frustrating, but the worst example is Zantetsuken. You don't really have a way of knowing if its actually active and it just wipes entire parties by surprise because there is no audiovisual feedback. The same happens to things like AST's Celestial River where nobody really knows if they got the buff/debuff unless theyre looking at their buff bar. please add some sort of aura or vfx to limit breaks.

- Party Queuing
I understand, to an extent, why parties arent allowed to queue, but it really kills a lot of the enjoyment from not being able to queue with friends even in casual matches. It's worth mentioning that preventing party queues does NOT fully stop people from queuing together, as you can still queue at the same time using limited language settings on the duty finder. Rather than making people use awkward work arounds for playing with friends, please allow some sort of party queue, with restrictions if deemed necessary. At least let us queue in a party of maximum 2 people, or make it so that even if we arent in the same team we can at least be in the same match.

- Purify
Given how every job has powerful CC, can purify get a 2nd charge, even if the cooldown is increased?

- Instant portrait
Its pretty obnoxious to have to set the portrait every time you change job, can it be made permanent, or make the game remember which job has which portrait automatically?

Some of these changes are small, others not so much, but i think they would would vastly improve the PvP experience.
