Goblins are easy, you can use those some things against the goblins. Gale is great to have cause he has Grease and Sleep, and Astarion is just amazing when tackling goblins. Make sure you get the high ground, you get a higher chance to hit and higher chance to dodge/get hit less when up high .
Lae'zel also can learn abilities that give enemies Frightened status too. With these three you shouldn't have much trouble imo(I was able to clear every fight with these guys ) .
