I have a good friend in my 4e group who is good when it comes to roleplaying his character, but he's always been a dedicated 3.5e player, to the point of avoiding 4e and even Pathfinder completely. He's one of those "why would I try anything else?" kinds of roleplayers. I managed to entice him into our game mostly because of the plot, but he isn't managing to grasp the logic of how 4e works.
He made a Dragonborn fighter, and ever since he's been complaining that he lacks the low-light vision that the elf and halfling have.
He seems to not understand that powers have no improvisational uses during skill challenges:
- trying to cut ropes with fire-based at-will powers
- trying to make the Psion use Far Hand or Far Push to launch him through gaps
- trying to then "exhale smoke" from his mind and use an at-will to light wood on fire
Another time he tried to get the sorcerer to use a Dragonfrost at-will to extinguish lanterns during a fight, when he could have done just by standing beside them and using a Minor Action.
Yesterday we were fighting a giant shadow solo monster with a weakness to radiant damage, but he argued it was illogical that it wasn't weak to fire powers if it was weak to light-based powers.
He's also been asking for the cleric's Rebuke Undead to act like the original so he can use it as a ritual and one-shot undead
He's asked to use the flames of his Flaming Weapon +1 for roleplaying purposes and to disarm traps, etc.
And so on.
Though the rest of my players do seem to understand that powers outside of combat can't be used to solve challenges unless they're utility powers or skills, he seems to want to add extra rules to every single combat power.
Despite all that he hasn't been disruptive, and a fair share of the other players look to him as a "leader" because of his attitude, mannerisms and character. Still, it's really disruptive to have a D&D veteran trying to turn 4e's logic into something more like 3.5's logic. I see 4e more akin to Final Fantasy Tactics and such.
It's becoming really annoying since the rest of the players follow the rules as written and like them, but they refuse to help me talk to him since they feel it's my job as the DM to do so. And believe me, I've talked to him.
