You're correct...there are none of the usual/popular game mode templates provided for us to use in "Custom" Portal mode.
... and there needs to be, if you want to play with bots in Conquest or any of the other usual/popular BF modes.
You'd think that before cutting us off from bots in Portal they would have at least provided us with a bunch of custom templates for Conquest, breakthrough, Rush, etc so that all we'd need to do is select "botfill or static bots", a difficulty level and the maps.
They're so smug about it too...I mean they didn't even bother saying something like, sorry guys but dont worry we are bringing them back soon with custom templates that everyone can use to play with bots in all these modes:" x, x, x" in Portal....just give us a couple weeks to work it out.
Nope, all they said was something like "we will think about some ideas to bring the bots back at some point in the future", and oh yea we still get to keep your money.
