"PvP is not balanced around 1v1."

As a Holy paladin, you will do just fine against rogues, providing you roll with at least one DPS buddy. Wait until the rogue opens on your buddy, then introduce him to your Hammer of Justice and see how he likes being stun-locked while your buddy blasts the heck out of him. If possible, help your buddy out by applying an offensive Holy Shock followed by Hammer of Wrath when the rogue gets low. Follow this advice (and don't get caught alone) and it's basically a question of whether the rogue succesfully runs away before he dies or not. Judge Justice if you can.

/runs 2s and 3s with a Holy Pally healer; does not fear rogues.

As a rogue, I can tell you right now the classes I fear the most are Warriors and Holy Pallys. Holy pallys just DON'T DIE! You cleanse all my poisons and blessing out of snares. Sure I can kick your holy spells and lock you out for a short time, but you are still a plate healing class. You can whittle us down over time and just win in the long run ^.^
