Why is Borderland Ruins Secure the worst Frontline map?

[OskarXCI]

Probably because it was the first map they ever made. Compare Secure to Danshig Nadaam and you can tell they're a lot better at designing maps. Not that Onsal is without flaws, but its flaws are a lot less significant than those of older maps. I'm not sure, precisely, how to fix Secure.

Just so you know, Secure has already received a makeover before. It used to be about 40% bigger and less open. More rocks and debris scattered around breaking line of sight, as you suggested. The stairs that lead up to 3 of the bases originally wasn't there. You had to go by the edge of the map to reach those. I think the original intent from the developers were that teams would split up into three groups that fight over the adjacent bases to your home base and then push into the spawn area of an enemy team, for the entire match. No running in-between left and right except when it was time to go to the center of the map for drones/node. Slower mount speed and the time limit was 30 minutes back then. If you/people think Secure drags on now, it used to be worse.

But I think we all can agree on that the TR needed to win a match need to be lowered.

No, what they're saying is what would happen if they removed invulnerability... and why it was added in the first place, back in SB. Experienced players would just farm newbies over and over, literally spawn-camping them. Removing invulnerability is a horrible idea. That's what they were saying.

Situations like spawn-camping would be less likely if they removed the respawn invincibility. Matchmaking is now random and premades are limited to 4 players. It used to be faction-based matchmaking and premades could be 8 players. While adding invincibility improved things on Seize and Shatter (Onsal wasn't added yet), it made things worse on Secure. It lead to less engagement between teams which in turn made matches last longer.

If spawn-camping is a no-no, then they might as well remove the bases from Shatter. No point in trying to claim them if you have little to no chance of holding more than 1 base for longer than 30 seconds.

Slauter Secure mode was removed because up platform

They never said why but I can guess that they removed the Slaughter version of Borderland Ruins because Shatter was more or less the intended replacement.
