Between summoner premades nuking entire teams
to Paladin's cover stealing nodes in Onsal
To nodes near consistently spawning everywhere that benefits the enemy team but not my team lately (since they don't spawn based on which team is winning or losing so the winning team can keep getting node spawns in their area exclusively pretty much guaranteeing their victory)
To being grouped with people who ignore call outs and objectives, can't kill or take nodes, and being grouped against constant meta abusers but somehow rarely grouped with teammates who are wise enough to abuse the meta themselves (I'll often be one of the only few summoners on my own team against teams with over half their teams summoners)
To countless games where it is obvious 2 teams are coordinating against 1 team (who is already in last place as second place NEVER focuses 1st but ALWAYS last)
It's absolutely unbearable for the solo que experience. There is nothing resembling enjoyment left save for the few rare close games. Rare, because most games nowadays just 1 team getting rolled while one throws a match for another. There is almost never anything resembling proper sportsmanship. Just abuse of broken jobs and mechanics, 2 teams ganging up on the 1 losing team rather than a proper 1v1v1 as was intended.
And what's worse is this is the only active PvP mode left save for the new, and now slowly dying, Crystaline Conflict. You took away Rival Wings rather than fix it and put it on the roulette. The one and only reason Frontlines still exists is because of the daily roulette rewards. Take that away and it dies and takes PvP as a whole with it. This isn't an enjoyable mode, and it never was. Largely because of the players themselves who refuse to play as was intended. But the game mode, along with certain jobs, being outright broken only leads to player abuse as we currently see.
It's an absolute clownshow. Is this what you want the player experience of PvP to be? Why does it even exist at this point? If you're going to leave it in this godawful state just remove it like you removed Rival Wings, let Crystaline Conflict die the death it also deserves, and do what I suggested in the past and completely give up on PvP since you refuse to actually give a damn about it and take it even vaguely seriously.
