Well i hate it on slayer but if it comes to dominion then its in my top 3 maps and yes solace is bad.
Honestly, I don't really play regular slayer much, if at all, in this game. At least I haven't much. The instant respawning really makes it weird. Nice on one hand, cause you're not stuck waiting around for 5-10 seconds after you die, but the constant respawning definitely changes the way matches flow. SWAT is already a fast mode, so I play that for my Slayer type and otherwise stick to objectives when I play.
I could see it being too big for a regular 4v4, though, so I can see why you'd hate it for Slayer. Would be nice to have some bigger teams or multi-team slayer matches as big as some of these maps are, honestly.
