I normally play tank characters, but in a recent game I was called out by the enemy team for being a bad tank. Frankly, they were right too, I was unable to protect my carries from them. THe problem in this game was that I was cho'gath while my enemy top lane was shen, so he could randomly be in a fight whereas I could not, so not only was my team usually outnumbered in fights, but my mid laner also was completely stomped in lane, only having boots, a RoA and a blasting wand by endgame. Our AD carry was teemo, who was I think AFK for a portion of the game and was also behind, but I'm not positive on that.
The way I usually tank is by getting in the enemy's face throwing out my CC skills at them, and usually we just steamroll right over them. Unfortunately, my team was behind, so we had to back up whenever engaged upon because they generally had baron on them. I tried the same strategy of running into the enemy team hitting them with my skills, but they just walked past me and killed my carries anyway.
(ACTUAL QUESTION HERE)
It all comes down to: what should I do to tank in fights where my team is behind? should I still try and push the enemy back? or should I use my CC to try and focus on protecting my team instead of pushing the enemy away from them? Or was this just a matter of my team being to far behind?
