All the playstyles you mentionned here are almost non viable.
Horse crossbowmen are non viable because of 20% damage and horse speed decrease + 15 damage cap for horse ranged (HT and HX included for now).
About the thrower, maybe you were used to 1 hit kill before with a lance, but now, you have to throw two throwing lances into someone to kill it at full life, even archers survive one lance.
And about your two handed cav ... don't know, but it should become a regular horseman with a lance/1h, since you gain almost nothing to use 2h compared to using a 1h with shield on horse back from what I see on servers.
Also, levels had been changed, means that your level 30 characters will become level 35, and your level 34 will become 37.
I hope this helped you a bit, wish you good luck, and welcome back.
