I had to agree, is a perfect sinergy. Unless you want MAX block, by getting peltasta 3, but I think this not worth it, because the skill on lv 10 is not toooo much inflated than on lv 5.
Another build is using Hoplite, but you will need to like use spears. , and be the style of Leonidas.
Hoplite Finestra amplifies the skill High Guard of Peltasta 2 really great, and you still you do much more damage than taking Rodelero 2.
But by using Spears will be much better if you using Dragoon as the final class, or even Cataph, than using Fencer, even if you had to be making swaps of weapons since High Guard of peltasta only work with Shilds, instead 2 handed SPEAR, so will depend on the situation you are on.
So you can make for example:
s > pelt 2 > hop 2 > cataph > dragoon.
s > pelt 2 > hop 2 > cataph 1 > cataph 2.
s > pelt 3 > hop 2 > dragoon.
s > pelt 2 > hop 1 > cataph 3.
But are even more combinatios, like:
s > pelt 2 > hop 2 > dopel > dragoon
