Dragon Soar is good but it’s only one skill. Dragoon is only “strong” because it has two defense-ignoring attacks, soar and Dragontooth, one of your strongest attacks when you factor in the spear lunge, a wide and long hitbox, the helmet, low cooldown, defense ignore, and bonus crit damage. It’s your sept etoiles or sturtzhau and it’s better than both, so don’t put one point into it.
Deeds by itself might be stronger than sharp spear (which has easy levels from the zega spear and has an attribute, which deeds doesn’t) but only because it applies only to crits. You know what else hoplite has? Finestra, so you can crit. And stabbing, which is far better than cyclone for single target with spear lunge (you get that too), spear throw for a much better method of setting up dragonfall, and pierce with the dragoon helmet, a very good bossing skill. Of course hoplite has synergy.
Just don’t try and force doppel into a goon build like this, it’s not one circle out of ten any more. If you want to take both barb and doppel then drop dragoon, you’re hurting yourself.
