Have the cockroaches spit faster, it takes around 5 seconds for them to do their spit attack.
Add encounters with guys that have high luck and Better Criticals perk, but weak weapons. Actually, more different encounters would be awesome.
Add a area that unlocks after finishing the game, that has an optional boss...
I can't do anything about the speed of the roaches' attacks.
Yes, more different encounters would be good. But, it takes some serious planning to devise ones that seem interesting and balanced. In some cases new encounters can't be added... there is just no room. In other locations on the worldmap there is room to grow. The Fallout 2 XP mod attempted to make things a little more interesting on the worldmap. I have included some of these. But, as I said, there is still room for growth. However, this rates up there with my "something needs to be added" comment in my readme file. If you've got other specific suggestions, great, lay them out there. But other than adding a couple of perks to the bad guys as you mentioned in your example, what else you got? (As for your example, I am not going to waste space on adding in more encounters with raiders, claim jumpers, slavers, etc. Instead, it is easier to modify those scripts to randomly add in those perks from time to time. And still I might not even do that, because, while you might like such an encounter, many others may not.)
And what is the point of this end boss? Why have him? What does it add to the game? Do you already have a location put together or maps created? I am not about adding in stuff to the MM "just because". Well, I might, if it was really easy to implement. After all, there is a lot of empty space on the eastern side of the worldmap. But, taking time out to create such things only detracts from me being able to add in those weapons, critters, locations, and quests that do add to the game.
