ok then a bit history for you
07 - Ham and Alo took many points away from each other, while Raikkonen had Massas support, thanks to this, he won the WC, and still it was Hamiltons first year in F1, and he already beat Alonso.
08 - he won the WC, not gonna say anything
12 - he had a bunch of technical problems, 2x or 3x time he had to give up the race from the 1st place, 2nd thing is that the pit crew was garbage, they fucked up so many pitstops for him, and since the 2nd half of 2012, Red Bull dominated everything.
14 - he won the WC
15 - he won the WC
16 - same as 2012, he had much more problem with his car than Rosberg had (i hope u remember the bunch of problem on qualifying, and the engine failure in Malaysia from 1st place)
edit: in 2k16 he had to race the 2nd half of the year with !!3 USED!! engine, while Rosberg got the new engine upgrades every time, Hamilton had to race with already used engine since Italy.
