Russians/Ukrainians always play pudge, Ursa or Huskar, (in any case always carry), play only mid, want 4 tangos and don't even say please just "giv me tango kotol" (if they speak English at all), fundamentally impolite, they ping way too much for no reason or if they suicided and expected you to help. When you gank them they make really retarded comments like "jajaja 5vs1" in every second sentence there must be cyka bliat or pizda, if all in your team are clearly English and you even tell them "sry but noone in this team can read any of these hyroglyphes" they still keep writing in Russian the whole game. they always push until they die even if they are now 3 and all enemy is reviving they keep pushing.

it's not true for all Russians but 95% easily.
