So you got a 10% bonus for a lot of hard work and 2.5% pay increase, not bad, I know people who haven't had a rise for 4 years and asked to do more so in that respect you've done quite well. If, however, you have been asked to take on a lot more responsibility then maybe not such a good deal, your call really if you feel you have been shafted then have a quiet word with your boss and see what the reaction is. They maybe testing you out and if you let this one go then they'll maybe see that as "weakness".
