I am 100% against more combat random events. As a matter of fact, I think that most of the existing combat-oriented ones have to go. The speed of moving around in UR is already a hotly debated topic (with people complaining about it or using speedhack), and random events make it much-much worse than it already was. Having to move around with your guard up *in already cleared locations* is just too much, afaic.
To make matters worse, doing rounds of shopping, another hotly debated topic, is also made much worse with random events. In particular, visiting Blaine, Rail Crossing or Dirty Tom becomes orders of magnitude slower because of random events. I have to take off my rathound regalia, put on a tactical vest, and enter stealth in order to visit these merchants. What was already tedious becomes totally misguided, imo. It is not like UR doesn't have enough combat already.
As a matter of fact, if there is ONE good thing about the shopping rounds, it's that they allow the player to forget about combat stress for a while. This becomes obvious in DC where there are no shopping rounds, and the constant combat stress becomes too much for a lot of players. To some extend, combat random events introduce this DC problem in the pre-DC gameplay.
That said, I have nothing against non-combat random events. I like them. The wounded man, the couch, the mute fisherman, the dead trapper are all fine. I also welcome the random events that are strongly connected to story events, like patrols clashing, the free mutants or Daniel Arda coming after you. But rogue robots, just another lunatic/ironhead group and the like? Those add nothing and make the game actively worse, for the reasons explained above.
My 2c.
