Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This is the build that I use in 5v5s and it works well for me. I get ghost and exhaust so I can run and chase first of all. I get force of nature to keep me on the field which is the reason for the many pots also. I then get warmogs for health and regen then get armor and guardians for armor. The masteries I choose for all defense and then for the summoner spells. I got random runes because I can't get runes yet so I just went armor, magic resist, health, and regen. I chose the skill sequences for max harrasing and slowing. Hes basically a stay alive harrassing tank that is best against a 2 ap, and 3 ad team.
