It'd be great to be able to define a static set of NPCs instead of them being chosen at random from the configured list. Even better: Support for multiple NPC presets in the config which could be chosen at random on each event (maybe even with a weighted % chance configured for each).

This would allow for different "strike teams" to be deployed rather than an RNG of the NPCs defined in the config. For instance you could sometimes get a very strong team, other times a team with Scuba gear & Harpoons, or Santa hat wearing Snowball Gun weilders, or hobos with Eokas ^_^
Could add some more fun and dynamic elements to this already good plugin :)
