there are differences between you playing Vondel and Rebirth Island. In Vondel, u can easily get kills(like 40 or 30) and you're very skill at that map. That's the pros but the cons on the other hand, you're very terrible at Rebirth Island(since the map is very small), you get less kill and very unskill. So I feel like it is better to play Vondel. Also u need to know that u can buy Specialist when u have enough cash
