Clunky UI is a clunky UI for example. Tactically uninteresting combat...
For me, these are just words. I don't find the UI clunky. Nor do I find the combat uninteresting, tactically or otherwise. That's why I find it hard to take seriously.
For instance, if I happened to be in a restaurant enjoying meal, surrounding by numerous other people also enjoying their meals, and some fella sauntered in and claimed the food was bad, the utensils barely worked and the service couldn't be relied upon... I'd roll my eyes and keep eating.
I appreciate that people have different tastes, but I'd argue that some people's "tastes" mean they're incapable of recognizing a good thing when they see it. What I mean is that if an enormous number of people like pizza prepared one way and you don't, it probably means you shouldn't open up a pizza joint.
