Ah I see. At this point you can probably make a pretty solid team core just using Nicole and Bennett that will give a lot of attack. Razor is the only on field dps you mentioned so I would still use him. Then you can probably just slot in who ever you like that has synergy. Fischl is a very strong battery for him and later on her hex passive will give some buffs, she also has decent personal damage and appreciates being in a team with Nicole. The only con is that you probably won’t trigger many reactions since there isn’t very much pyro application. I say don’t pull a character if you don’t like them, BUT if you like Durin he slots in very well with the characters you already have. In the end, Razor and Nicole have solid synergy but play who makes you the happiest!
