So if you (take the admittedly very generous) position that the number of raiders has tripled, then there are three times as many tank raiders now than before.
This doesn't mean that there are three times as many people who want to play tank of course. Just three times as many statics (more or less) which just so happen to need two people playing tank. It can't be used to gauge interest.
