banner of command,Tank karma and veigar rant post

Just finished a cait game i'm pretty salty about, won lane, top won , mid was okay...won every single team fight....won all drakes...then lost 1 fight because karma and veigar are legit unkillable with a soraka in the botlane,lost baron and elder and team fighted one last time , took me over 6 seconds to kill a veigar whos caught by the entire team while our kata fought off the rest because of how fucking ridiculous his tankiness is while being able to oneshot me. positioning was perfect and I didn't stop autoing all fight but it's just not enough with excutionners and morellos it's just ....not enough to kill them whatsoever and they were still able to deal a disgusting amount of damage. also whats with this banner of command shit ? just so frustrating to get these cheesy ass strategies every game like early game doesn't matter at all...falling behind should have harsher consequences than this what the hell man.. opinions ?
