Guild Wars 2

Hey!
I started to play in december of the past year and reached diamond few days before of the end of the s1.
Well, I had not difficulties for reach emerald. More and more 3 wins and reached more ranks of emerald in a short time(4/5 won). What’s happens? In one match, my Internet crashed and I came back hours more later.. that was terrible: I won 4/5 matches before and after I won 1/10. My MMR was changed with the crash to a many low MMR? In the last rank of emerald I had to make a group with people of my clan for try increase my mmr, at least this last night in premade of 4 diamond(scrapper, ele, dh and me), we reached shapphire.
This thread is for make a question, how many change your mmr after of “Desertion”? That was not normal, the “desertion” match was being winning and after.. every match lost.
Actually I win 3/5 games or something similar in shapphire.

I have 526 rankeds played(252w/274d): 47,90% w/d.
