Would you play lockdown different if the spawn no longer had a respawning heart pad?
Would you play different if there was a wild "GOLD" Trojan wandering about?
Would you play recon more if your steps didn't send up clouds of dust in certain arenas?
More a bunch of questions than a suggestion, I just want to know what you think about these ideas that pop into my head.
1) Getting spawncamped would suck much more. Also people would probably actually use guardians to heal, but that's embarrassingly slow.
2) Only if it gave items or some kind of other bonus, but otherwise, I see no point in having a monster walking around in a PVP game. At least rock jellies are slow/rarely-spawned and don't cause too much collateral damage. A trojan would be huge, block shots, tackle all over the place... in general would be a really annoying stage hazard.
3) I already do. I'm of the philosophy that "footsteps" are part of what any skilled recon should be able to play with. There are ways of using visible footsteps to misdirect people, and ways to play without having to stay cloaked during the entire approach.
