I play hoplite for a long while and I find it perfectly viable. It isnt underpowered or underpowered, as anyone with a degree of understanding can utilise it to terrifying levels of efficiency, but not any idiot can just pick it up and pose a threat.. Pully is by far the best hoplite Ive ever seen, but I like to think I can be posed as a challlenge somewhat for any player. Ashwood pike isnt to my liking though, I would stick with a warspear. People think they do the most damage with an ashwood pike, they are however, wrong. Unless something drastically changed in the coding of polearms with spears, I recall that any polearm over 150 length used with a shield gets a 35% damage reduction, the same as a longsword/heavy bastard sword would get with a shield. Which means with the 166 length ashwood pike you get the reduction, but you dont with the 150 length warspear, giving you more damage overall.
If you want a long polearm to use with a shield, use a bamboo spear, its surprisingly effective.
