You can use Thrust with the art to move out quickly. Always worth 1 point for the utility.
Yes, the Glacier shield is a bit much, but not because of the freezing effect but your complete reliance on this specific shield to deal considerable damage with a shield-based build.
The skill factors look nice on paper, but then you realize that you’re only living with the damage boost from Swordsman unless you replace at least one class of you three with Doppelsoeldner or Barbarian(at least it’s easy to stack Frenzy now).
If you replace 2 and only keep Peltasta, your class attribute will only boost your damage marginally, and also your Glacier Shield efficiency will drop drastically, meaning you’re forced into Peltasta>Rodelero>x to use the shield efficiently and to deal damage with a shield build.
Now here’s the question,though: how do you get a decent crit rate on your build without either using a sword (wastrel sword ichor) or a moringponia shield ichor? You’ll need Hoplite or Matador to compensate for the crit rate lost if you either use rapier or spear with the shield build.
This in return gives you less build choices again, unless you can live with a low crit rate, ultimately forcing Peltasta out of non-sword builds if you want to keep the Glacier shield utility, meaning Rodelero>x>x…
