If you want to go that Class route, use 2H, and have a high skill count, I’d go with this:

Restrain’s usefulness, especially at level 5, is significantly diminished now that enemies don’t hit so hard, alternatively, Gung Ho and Concentrate are fantastic damage increases. Utilising Restrain is still possible, but for PVE I recommend opting for this.
Stabbing is a great skill when combined with the debuffs, and Pierce is really only a useful filler and the damage is better spent elsewhere. Long Stride has a high CD, slow animation, and annoying CC and for my preference I’d remove it and point another point on Spear Lunge, but overall it would increase total skill factor damage so you may want to use it.
Serpentine’s Piece type means it does fairly high damage with Spear Lunge + the Serpentine debuff, and Dragon Soar does an okay amount of damage. The rotation that you will rely so heavily on, especially as a Hoplite, is greatly improved with what I’ve given you, meaning without Gae Bulg. Gae Bulg has bad CD, overall less raw skill factor, and slows the entire skill rotation down through its hitbox and animation. It is possible to use so if you want to, you can, but I don’t recommend it.
This my personal build, it focuses on low skill count, sustained DPS and future viability:

Short term I am considering making alterations to this though, as I have a few seconds of skill downtime:
