NPC Base Raids

I still like the idea of base raids, and I do want them to return in some form, so I've got a suggestion.

NPC base raids.

A couple of pre built bases. Shouldn't be so hard as devs have all the resources. Set up arena style except every member on each team has to be in the same SG. It also requires a certain amount of prestige to be spent, hopefully making it a bit of an inf sink. The winner has the inf refunded, the loser loses it to cover base damage.

There could be a few modes or ways of winning to this. One involves dropping pylons, like in the old base raids, but maybe these one supress powers instead. Or destroying items that hold them. Or by x many kills.

Once in, the defenders have x amount of time to set up, group up and get ready. After that amount of time, the attacks spawn in a random room and given 10 seconds immunity to prevent spawn ganking, which also supresses travel powers.

The defenders also have turrets set up around on their side, maybe have them set up to do various damage types and randomize their spawns. They also have a single power generator room set off to the side, which destroying would bring down the turrets.

Maybe for rewards, grant special base pieces, badges, and even something similar to items of power. I don't see why they removed items of power, when it was the fed-ex bug that made CoP trial the exploit.

So what do people think?
