The tigers have won the majority of the new arrivals, and if it wasnt for disloyal castaways swapping islands, they would be ahead by far!
This puts tigers at a disadvantage when attracting new arrivals as some people may not want to choose a team who are so far behind people wise.
If no-one had changed islands throughout the tigers would have 10 people to the sharks 8.

yeah i no tigers may be winning all the new arrivals but it's the ones who are there that are proving disloyal

Also, if new arrivals realise so many people have swapped off tiger island, they'll think there must be something wrong there, so are less likely to pick it. All in all it isn't looking to good atm, but the numbers seem to change quite dramatically every week with all the swapping, so who knows what it'll be like after next week.

The problem is that lately the new arrivals have been picking Tigers for very superficial reasons, namely because they fancy the girls, and not because it's a place where they really fit in. This is leading to a fragmented group dynamic on Tigers, which is causing people to leave.

In contrast, the few people who have picked Sharks seem to have done so after thoughtful consideration of the dynamic.
