What does it take to get allies to coordinate with their tank?
I love playing tanks. I love being in the front line. I love being the initiator. I love being the one to lead the charge, the one who calls the shots. I love being able to survive focused attacks for an obscene amount of time. I've sometimes lasted 30 seconds of an entire enemy team chasing me down, burning all of their resources just to eventually see me dead only to wind up erased by my allies.
I have no issue with items, honestly. I research cost effective builds and attempt to apply them to my situation. My personal favorite is combining Righteous Glory, Warmog's, and Deadman's Plate. If I need magic resist, Spirit Visage goes well with Warmog's and Righteous Glory because of the health regen I receive. I'm able to siege enemies perpetually with my builds.
My biggest problem I run into, however, is trying to convince allies to fight with me. Half the time, it doesn't seem to matter how strong our team fight potential is; they just don't want to group as five for an easy win. There's no need to prolong a game past 30 minutes if we're able to win one team fight and obliterate the enemy HQ in under a minute. But they almost never do.
