My guess would be that with the new combat system the whole thing about auto attacks in interlock are pretty random and when you spam abilities they usually have a sort of temp buff that make them hit. Like if you have speed on you have a 10% chance to hit, which would go more towards a special than towards an auto attack in my guess. In my experiences you hit with specials alot more than with auto attacks no matter what the lvl your fighting. I have faught NPC's and players up to 20 lvls under me and no matter what they always get auto attacks in. But my specials almost never miss. That's just what I think.
