I like the idea of frontlines, I do.
When I choose to PVP, because I hate the Wolves Den and everybody there is awful and nothing will change my mind on that, I go with Frontlines.
The problem I have with frontlines is, though, it's incredibly boring. The whole battleground is rather uninspired and basically just results in some League-of-Legends-ripoff PVP. It's not really engaging. It really all amounts to "Go to the left and get point X, other team goes left to go point Y, and maybe have that other team camp central until Z spawns". Can we get some better PVP battlegrounds aside from the flats?
I'm thinking something like the Corsair's Stronghold from TERA. You know, lots of stuff to interact with, capture, destroy, to better help you take over points and get a better foothold over the other faction. I mean, really, anything would be more exciting. 2 vs 1 maps where one GC gets a fortress with gates and weapons to help defend the fortress, and opposing factions get siege weapons to help break into the fortress and accomplish whatever the hell the goal would be, and then cycle through with every 10 minute round.
Or a big canyon where GCs have to take turns escorting convoys through to the end, where the distance traveled generates points and every vehicle that makes it through generates bonus points. Attackers generate points for every vehicle/NPC destroyed, and can slow down the other attacking GC by capturing spawnpoints closer to where the convoy is. The defending GC can place traps along the way in the lanes leading to wherever the convoy is located, like bear traps, mines, poison gas, or puddles of tar/mud/whatever to slow anyone who runs into it.
I dunno, I'm just spitballing here. I don't like the typical "capture the points to score more" PVP. I get that my ideas aren't as "skill" heavy, even though PVP doesn't require a hell of a lot of "skill" to begin with, but the point is just make frontlines more entertaining and fun to play. Right now it's pretty bland and generic, with not a whole lot differentiating it from other games and their PVP, despite its massive potential to be way more fun to play.
