Valkyrie +++ looks kind of obnoxious.
Pyromancer and Hydromancer look a lot more useful.
Frost mage is less sad now, assuming base frost mage got upgraded to frost mage+'s old set.
Royal Guard+++ getting changed is fine, though I'm concerned if it costs the same as Ghost++ like Main said. Swap might be more in-character with royal guard as well for the 'get behind me, sir!' sort of flavor.
These formerly stationary pieces like Beacon and Portal gaining a move square on their own is kind of strange... And also makes me wonder if thunder mage will be worth it anymore.
Does hoplite+++ also share the attack move with other hoplites or just move them in the same direction without letting the adjacent hoplites capture?
The frostmage assumption is correct, this affects base and + only.
Also, hoplites share only the move itself (no multi-kills),
but I'm still not sure the accurate value of this hoplite+++,
this one is mostly about buffing the lower tiers.
No multikill (as Grand said), but already in current version, if hoplite uses attack "part" of the move+attack (black) square, other hoplites beside it do not take move forward even if their path forward is free.
