Okay, first off, I'm not entirely serious about this, but I saw this in a dream I was having about cRPG and thought it might be interesting to share the idea anyways, just in case :p
So, in my dream it was pretty much normal cRPG, except when the flags came up to become mater of the field, there was a way to trigger an optional 'Boss' spawn. A bot with high stats in everything, twice as much health as most characters, and a randomly chosen set of gear from a list of gear sets.
If you were to manage to kill it before the round ended, you would earn additional xp for yourself and your team, scaled up by whatever multiplier is currently held.
...of course, my dream was in the highly unlikely scenario that i was the last one alive on my team with the flags, which would never happen because i suck. and for some reason the boss ended up being a pirate. But details, details.
