Combat was easily the worst part of PST and any changes they could make to it would be for the better.
The worst part of the best game of all time isn't high slander. And you consider it trash, but there are plenty of people who didn't have any problems with Infinity Engine. It was more or less the perfect fit for faithfully bringing AD&D to single-player PC games, and I absolutely love every product which shipped with it. That the core of that system went on to power the seminal KotOR (and less than seminal NWN's) is evidence enough that I wasn't the only person enjoying it.
