Summon liegement probability

fatty

Dear sir,
I found that the probability in liegement summon is harsh.i play in few servers but always repeat n keep repeating the low or common liegement.those rare heroes cant say rarely show,It should say it totally not showing up at all.maybe I am not from old old server but this is the sound of some players.for example,no body get guanyu,zyun,zoo ci,liu bei,zgliang,squan,saying,lubu...etc.....can u pls adjust the chance for those nice heroes for summon,no fun at all to take the same for days,weeks,months even years.....except raise chances,maybe u can create more matches in liegement then must hv more fun.
Hope this msg can reach u or help also.
