I find your hoplite vs 2h sword reach argument a bit strange though.
Yeah, I kinda feel like Tydeus was just grasping at straws coming up with the whole "2h stab must be longer than horse lance or hoplite stab!" thing. Regardless, the fact that this could even be considered a valid argument just shows how spoiled the 2h class has been this whole time. I can't think of any 4D polearms that would even be able to somewhat reliably outstab (or even stand a chance with any swing againt) a lancer's stab, other than the long voulge, which can't even rear the horse, or the fauchard, which no one uses since its simply garbage, or the military scythe, which frankly isn't too common either. The glaive might be able to stand a chance, but I don't think anyone with a glaive would ever try to outstab a lancer when they could hop safely to the side and rightswing. The only people who should ever even think of stabbing against lancers head-on would be long 2-directional poles or the 1-directionals.
There is no reason losing reach on the 2h stab would be so insanely detrimental when the animation may end up acting more like the 1h stab and give absurd speed (in return for the lost reach). The 1h stab accelerates through the animation so fast that it can pretty much hit without glancing at full extension. If the new 2h stab acts like that, while the old 2h stab (supposedly) could only hit at 70% extension, then the reach lost isn't that major anyways.
Also, on the whole argument for why so many people choose polearms over 2h nowadays... don't people ever consider that it might not be a contest over which class is more OP than the other, but simply a contest of which class players find more fun? I was a long time 2h player before I finally switched to polearm. I did so because at the time polearm had yet to be buffed and I had finally gotten to a point where I could be considered a decent player, and realized how OP 2h was. Of course only a short while after switching over the pole animations were buffed, which then led to a whole lot more people switching over. But did they all switch over because polearm was OP, or because it could finally stand on its own against 2h? Same goes for 1h after the 1h swing buffs... you see a lot more swashbucklers nowadays. Is it because it has become OP, or because it finally doesn't suck to play? Tryhard/KD-whore players have been stuck playing 2h for so long so they could perform well. Would it be so unreasonable to assume that they switched over to poles/1h because they were sick and tired of being limited to one class for what... 2, 3 years?
After the pole animations got buffed I considered going back to 2h since I hadn't been playing a polearm all that long (by comparison to my 2h time, anyways). But the reason I stayed as a polearm was because I realized it was simply more fun to play. I didn't do the same thing over and over and over again to beat people like I would find myself doing as a 2hander (grab a sword, feint overhead/stab, spam leftswings). Instead polearms offered a lot more variety and I would be able to choose a completely different playstyle when I got bored of the last. Polearms just have a lot more variety than 2h weapons do... your choices are more than just "sword, fast sword, long sword, longer sword, longest sword, 3-directional sword, longer 3-directional sword, good stabbing sword, good slashing sword...etc." and more variety often allows for more fun. With this upcoming patch it seems that 2h will be getting a good amount of new stuff added, new stuff that isn't just new swords, mind you, so that should definitely help more people stay as 2h because they will have more variety than ever before.
