Slaughter 72man is, and there is just no other way to put it, absolute crap.

It's completely discouraging to see that they just release these maps and rulesets and let them stay as was and not make even decent adjustments to rules and meaningful balance in future patches.

24man Slaughter (8v8v8) on the other hand works great(at least better than any other frontline mode) as it's engaging and you can actually make a bit of a substantial difference by playing well, while still not being as stressful as say an arena deathmatch.

Furthermore something that was completely predictable happened, yet again something the devs either didn't care about or are just oblivious to an extent i can't even understand, the secure mode died, and of course that happened as the PvP population in this game isn't that big to support 2 active 72man maps and the GC restrictions just make it even harder to manage such a huge mess.

Slaughter 72man just needs to go, its the easier solution, it won't happen, but still.

Large scale PvP is very hard to balance(VERY hard) and even harder to keep more than one large scale map alive and very few games i can think of have pulled it off or even try for that matter, instead they are reasonable and release maybe 1 large scale map every now and then, think 2 years or so in between for a good amount, just so it's there and those games have way larger PvP populations too btw.

These points are the reason why after releasing the first 72man Frontline they should have started making smaller scale(8v8v8 or simply 8v8 or 16v16 even) which would work much better and are much easier to get decent balance given the same amount of time.
Sadly , and although i wish it was not going to happen, SE is probably just going to keep pumping large scale maps for Frontline and as an almost sure consequence they will be broken in one form or another and to a greater or lesser extent, but still broken.
