First off, let me congratulate you on the release of yet another gem of a game. I have been enjoying the heck out of it so far, but I've noticed that using the weapons special attacks seems to be a very poor tactical decision (so far - I am around lvl 9 and have explored about 5 areas fully, and it seems all the special skills do double damage + ignore some armor, with possible secondary effects).
Basically, in the time it takes to charge up the special attack and execute it, which may miss either due to accuracy or just my poor judgment of the enemies motion, I could have instead had every one of my party members execute some form of attack, including casting spells, and be starting on round 2 of everyone attacking. One potential big hit is never worth it when you can attack 4+ times in its place, especially when you consider the party is usually still mobile during those 4+ attacks vs. standing still while charging up that one potential big hit.
I do like that I can choose when to use the skills, but I think they would benefit greatly from having a drastically reduced charging time.
Just my two cents

Thanks for the great game!
