Guild Wars 2

Always noticed my HP in heatlh pool is different as stated on stats window. Anyone know why is this?

It will be your WvW bonus.

As your server gains points in WvW certain bonuses are gained that effect all players on that server, one of these is health bonuses.

Press b to open up the WvW window and you should see the list of all the bonuses your server currently has.

Ah, never thought of that (not very familiar with WvW aspect). Thanks!
