As everyone who's picked up the starter knows, the counters included in the game are pretty flimsy, and there are an awful lot of them to keep track of.
I improved mine in two ways. I posted this on BGG, but thought I'd point it out in some of the other Anima Tactics places as well.

For the wound counters, I picked up a pack of thin styrofoam sheets from a local dollar store and glued the counters to them, using a different color for each wound value to make them easy to search through.
For the states, I got 10mm wooden cubes from a craft store and glued the state counters to the sides. I did some cubes with the 6 negative states, and some with the 5 positive states (counting berserk as positive), plus a blank face to use for 'Hidden'.
Much, much easier to manage and track states with these!
