Roaming

How can early game like level 2-3 roaming to other lanes turn out to be so op, i feel its that feeling were your like "If their was just a little more damage I could get him/here" then someone on your team shows up and throws a few skill shots that either zone or poke down the enemy that lets you land that finale combo you were looking to use but didnt have the means to do so with just your support who's scratching him self at your tower. Theirs also that were people who support are like night and day, their are those that do nothing but sit at tower then go full leeroy jenkins and die instantly then they say you suck or that your a shit adc, well their are the other supports that know how to ward, poke at the enemy to make them burn health pots and mana then once their down a few bars of health pings you to gives you a heads up he/she is ready to make a combo play and u both go in and just wreck them and manage to back out before the jungler comes in and cleans up cause your low health and he was just sitting in river bush waiting for the fight to end so he could get the clean up easy kills that an unskilled noob jungler can get that then makes him think hes an uber pro and can talk smack saying your crap. but as i see no one that plays league actually sees things for the way they actually are, if your dieing all they see is your deaths not the fact your only dieing cause of 3 vs 1 ganks and 3 ults and exhausts just the 2-3 deaths , nor do they seem to understand a ping warning them to not go near the bush they walk right up too 5 sec later and get FF by the whole enemy team that just ran into said bush they walked up and then they bitch at you for not following them saying you weren't their for the team fight. so thank god for the mute chat function, can finale ignore all those bossy dicks that want to feed you to the enemy team and rage at you for not following their agenda of feeding the enemy team so what do they do they denie the surrender vote untell you afk, since the crap surrender function gives the 2 trolls on your team control over whether you can surrender or not well they feed non stop calling them team fights that you weren't their for so they lost when their both 2/12/4 and 4 of the enemy team is 10/3/18 so league wants to make you suffer through the 2 trolls that you get very often through match making, otherwise theyd give us a better means to end a match that you cant play or are having no fun playing because of those 2 trolls saying "we got this".
