Riddle me this r/dota2

So I go into a CM game, all is well and good, drafting is fine ect ect. So we get a decent comp; invoker, veng, wr, sandking and silencer. they tell me to go semi-carry and go for dmg build. I'm like okay, cheap starting dmg is obviously some nulls + glaive (because who gets curse lol)

We trilane bot so wr can solo top and invoker mid. usual stuff. the game goes fairly even for a while and then wr for some reason just lets weaver solo farm top and tries to help bot out (which really didn't need help)

Fast forward to right before the end of the game person a: just let them push me: we keep doing bad fights by going to them person b: its not that. its you. person a: silencer why didn't you go more tanky you didn't need those nulls or dmg stuff. person b: its over because weaver has more farm than you person a: yeah, silencer didn't get enough farm to carry

I'm just kinda sitting there kinda going lolwat? I had more farm than our solo mid invoker (that only got 3 kills and saved the enemy weaver more than once) who I thought was supposed to be our main carry. Who puts it all on someone you as a group say should semi-carry.

I guess this is mostly a rant about people being dumb and confusing when you solo q. You'd think having 200+ wins would get you q'd with semi-intelligent people, especially in CM
