First-mover advantage?

[dingding]

I'm wondering if I am the only one that thinks the first-mover of the game (P1) has a special advantage.

It's quite obvious that at any turn of P1, he has 6-7 more wits accumulated compared to his opponent. P2, however, has only the same amount of wits at his turn as P1.

This mechanism seems to force P2 into a defensive position. Still, in some maps securing a strategic position controlled is crucial and turtling doesn't seem to be a very good option. Plus, 6-7 additional wits to P1 can be invested in a WMD (mobi or bombshell) which crashes the defense.

Would the game be more balanced if P2 gets an additional wit at the beginning (6 instead of 5)? Any idea?
