This whole "His arguments are wrong cuz he bad" are stupid, why? Because first he didn't even talked about mechanics, he talked about the game itself and it's fundations, second, it's a way to make a falacy, how? Ad hominem insults to his skill on the game and not on his arguments.
The things you were lied about were the distance on the map - existence of clans - the skill tree - the two modes of play - the server cap "UP TO 100" (when it only had 50) - the dedicated servers - Meld of PvE and PvP...
pretty much sums up the lie you had to deal with when buying an unfinished game that promised all that stuff AS A FULL GAME, NOT AS FUNDING (lol, if he wanted that, he should've gone greenlight).
Either one of two:
A) You're too blind
B) You're not as blind, but a bit "innocent" to beleive all of the statements above were true.
