Love it, very balanced and I already used many shards to try different company compositions, now I can also see a possible "end game" in lvling all my units to max lvl (before, choosing to lvl up a unit was a stressful process, knowing that it may bite me back if I wanted to try something new) and then I'd continue anyway to play to try different army compositions (and maybe new contents!).
This game has done great steps forward since closed beta, just a bit more AP balance for some units and then the devs can focus on new stuff (e.g. new maps, victory conditions and races, especially new maps would be welcomed!
)
PS: I'd like to have more time to play now, but the last weeeks have been busy and the next ones will be more...
