I remember someone speaking about Hoplite and I agree with his thoughts, with Hoplite/Pikemen you're always going to be slow due to the weight of the gear you carry, which is why I think it's better to go for a higher STR and deal with the agi when it comes to it, right now, most of the speed is decided on armour, so if you wear heavy armour, you're slow, whereas if you have a high STR level and go for medium-light armour you'll be better off as you are now dealing massive damage whilst also agile.
Edit: Found the quote of the guy I meant, he explained it right:
"I think AGI is not needed when playing as a hoplite. We already do low damage, we already are slow, so agility do not help us when we try to do hit-block-hit-block. Because of this, my philosophy is: hitting hard when you can. Due to this, I also do not spend any points into weapon master either. It won't help when you have a low amount in proficiency. Of course my build might be a bit overkill, but I'd advice having high STR to other folks in their builds."
(Keep in mind this is old so some points are incorrect, so ignore the crossed out bits)
I would recommend 27/18 or for a lower level 27/15
27/18 gives you a large advantage but 27/15 is better for a level 35 character, that way you can get 9 PS, 9 IF, 5 WM and 5 ATH, they seem low but you should then have a few left over points which can set you up for the level 36 which will give you 27/18, it's a less complete build but it favours you in the future where you can deal with all the points you've gained.
OR, if you want to, you could trade some IF for more ATH and WM.
So for stats you could go: 9PS, 5 IF, 6 WM and 6 ATH. It more or less completes the build but leaves you vulnerable to hits due to the low level of IF, which is kinda necessary due to the massive amounts of archers/xbows every bloody day.
