Tony, thanks for the reply and the builds.
I don't think there's much forced movement there, is there? And the self-buffing changes the character quite a bit. Can you build a viable polearm paladin? Might be a better fit.
The most viable 'polearm' paladin would probably be a lance charger build.
There is very little forced movement, but tripping, AoOs, and threatening reach (with Righteous Might, you become large, so the area you threaten is /huge/), make for /very/ potent control, more, I'd say, than you could accomplish with any fighter build of any level in 4e. AFAICT, 4e intentionally nerfed polearms' with the 'threatening' distinction and Close Burst weapon powers always being '1' instead of weapon-reach, to keep martial characters from trivially /becoming/ controllers. Yes, self-buffing changes the mechanics and maybe some of the specifics of the character, depending on how much you lampshade it, but that's inevitable when modeling the same concept under different systems. The basic concept - religious-warrior, using the pole-arm to dominate the battlefield - is easily modeled.
I don't think this is as close as your polearm tripper. Buffing with Tenser's doesn't seem very similar to Cloud of Darkness + Flame Spiral + Action Point + Cyclonic Vortex + Drow ninjutsu to put them in a lock and stop them shifting out of the darkness next turn.
I suppose there might be other ways to make up Drow ninjutsu... (?) even the Monk muticlass is an option, it's just that sacrificing caster levels is so sub-optimal, it's better to fake whatever you can with spells.
Hmm. A theme emerges here about "magic making up for things".
Sure. Magic is the most powerful resource, so you need to tap it. Aggressive re-skinning isn't encouraged like it is in 4e, but it could be done, though (as always) some DMs might just balk at it.
I missed the ranger spells. How is there healing and buffing?
It's been a while, they kicked in at 3rd level and were pretty druidy, druids had healing & buffing, but without cracking the book I'm not sure.
I'm not sure I can entirely divorce, in my mind, realising a concept from realising it effectively (or at least viably), but your effort is appreciated!
Though you're not really making me interested in giving 3E a second look! If this is 3E's selling point, give me 4e!
It's certainly the aspect of 3e I found most engaging - and, judging from all the 20-level builds on CharOp (many of which were optimize-to-concept, not just optimized), I wasn't alone. The flexibility of mixing each class/level like a building block let you do a lot of things. Sure, out of that nigh-infinite range of creatable 'builds,' there were only a tiny minority that were viable, and fewer still that could remain relevant in tier-1, but it was still a fun exercise to build to a concept (even if your creation wasn't always practical to actually play).
