I have seen IP or +20 at about 90% of the IDOC's I have done. It's always exciting and they have it down pat for sure.
I have respect for both the guilds just cause they have a good system in place to handle the IDOC's. Me and my brother are just a two man guild named BBinc. We have beaten both IP and +20 on multiple placements. But 90% of the time it's due to just plain luck.
We are both stealther's and move around between all the pk's and blues with ease. To date the biggest we have placed against them is a 13x8 which isn't shit honestly. But it's ok for 2 guys against 2 or 3 guilds.
When it comes to IP/+20 or even GG at IDOC's you have to decide if you want to loot or place. Don't try both. If ya loot get in and get out quick. If you want to place your best bet is a IDOC Stealther. If you are visible you will die quickly on foot
The best part with IP or +20 is they are cocky enough to think no-one is around when they drop the Classic holder to go bigger . Stick around a bit and sometimes you can get real lucky
Most of the times after the placement is done and they are hanging around outside they will shoot the shit with ya. Sometimes their reds will attack ya. Just depends on how bad ya pissed in their cheerios.
Anyways my two cents about two guilds that win alot but sometimes loose
