Hello everyone, I have a question. So, I'm fairly new to the ffg star wars rpg system and this is my first time ever running a rpg. I've been playing with a small group of friends for roughly 6-7 months now (I have 3 other players). I know about the 3 "classes" of enemies, the minion, rival, and nemesis. The problem I'm running into is that my players tend to go through nemesis like their nothing. I upgrade their dice to red (based on adversary talent) and give the setback when appropriate, but they still churn though them like in 3-4 rounds. I don't want the nemesis going twice due to overpowering the group. One one hand, if I "buff" them up, the pc's can't win. On the other, if I keep them the same, I feel like they get mulled over quickly. Is there something I'm missing in the rules or is the game design that way (for nemesis to be defeated on the quicker side) and I need to get better at role playing out what my nemesis are doing?
Also, my group doesn't roleplay good. What I mean by that is that a player will say that they are, for example, trying to take down an enemy, they just say, I'm going to attack instead of saying, I pull out my heavy repeating blaster and shoot at him. I've been trying to get more animated in what npcs are doing and describing there actions to give the pc's something to go off of, but I'm not the best at it yet. Any suggestions on how to improve this part of the experience right now would be appreciated.
Thanks in advance for all the feedback.
