I don't understand why you are talking about wards and carries when my message is wider than that. But to answer your concerns, lets talk about a straight 5v5 teamfight. I played a lot of jungle s3 and s4. When i get an adc going, is it normal that the ennemy tanks should be force to outplay my adc, since he is fed and can kill him. Now, they only farm (what a game) their jungle and when they come out they force all the team to peel for their adc and yet when you are skarner or sion they can reach your adc and put him out of the fight.
The REAL problem is that tanks now do the "tank" job + the "bruiser" job. Another problem is that some champions can now use the "tank" items and do as much damage that when they were full canon. I'm talking about fizz here. Jumps over your team, kill your adc 1.5 sec. I played a game I was vi, I was fed, i met a full tank fizz in my jungle,
. That was his build. My full combo did 1/8 of his hp. I didnt have time for a second one I was dead.
I played Nasus another game. Riven was 2/0 from roaming, and I was 0/0, but managed to farm till lvl 6. I REKTED her 1v1 at lvl6. UNBALANCED SHITS.
