[>BKA< T Wrecks]

Hehe... yes, sometimes you can get the cramps when watching the VIP... he's inches away from a rescue point, but then he sees an enemy, and instead of taking one step back and winning the round by escaping, he starts to fight the enemy... 9_9
Btw, there are even less WP types. There are no CT and T goal WPs. I once suggested adding a possiblity to make map goals team-specific in order to make maps with a goal for each team fully playable with bots. csde_tropic is a good example, or de_wallmart. In both maps, there are hostages to rescue, and there's a bomb spot somewhere. But the Ts often try to plant the damn bomb near the hostages because they don't know the difference between map goal WPs. Anyway, a whole new waypoint type would be too much for that. The possibility to add a "T only goal / CT only goal" flag (like with camp WPs) would be sufficient IMHO.
As to that VIP problem, I think the best solution is not in changing waypoints. What do you want to change, add "high-priority waypoints" ? The VIP already has one - the map goal. Or block passages for the VIP ? That would reduce the VIP's possibilities to choose an unexpected route. Or make VIP-exclusive waypoints? That would make waypointing as_maps twice the PITA.
I think any improvement to the VIP's behaviour should not be sought after in the waypoints themselves, but rather in the bot code, because the bot code tells bots what to do with the waypoints they have...
