The reason why that one connecting shortcut (lower PG to upper RL) is so popular is probably threefold:

• Right on the tiled floor on the upper level you have a player respawn point, placing bots right next to this "critical" area.
• Bots seem to have a preference for the PG *and* the RL (normal), so they will wander between the two weapons.
• And since a YA is also close by the bots will roam this area in particular.

What you could try is removing the player respawn point here, to reduce the focus on this area somewhat. E.g. place it inside the RL room near the hole or so. Might be "funny" to place the respawn exactly above the hole and have the player drop into the lower water area

Since I suggested changing the alternate TP exit, I like the exit near the LG. It gives the player access to the less frequented lower water area. I'm not quite sure the bots use this "secret" TP path though.

Even though the r_speeds are not really an issue with about 9K. But looking towards the water room, from the double-TP room, all the water room is drawn, IMO this should *really* not be happening. A final hint brush might be in order to better cut off the pool area.

BTW, I only recently remembered cluster portals: I no longer remember when they were actually useful (required). But those might be able to "balance" the bot play a bit, i.e. help the bots not considder large parts of the map for navigation, but stick to the current room.

To all: Did we have a good tutorial on cluster portals?

It's the three small healths. Often they went for these prior to going for the YA (in fact I didn't see one head off for the RL), and more often than not they took just one or two of them. I would suggest as a quick test removing them altogether (...)

I really like what you've done with the non-pure version and the changes you have made since the original beta. Thankyou for taking the time to share this with us, and for bringing back some fond memories.
