I've always hated the combat system myself it's just something I tolerate...
it's all flash bang sparkle and no actual substance or weight. The 1.23 one was much better every button you pressed had impact and was visually different also had a lot more depth with things like incapacitation break a bosses tail or something and the fact TP and MP actually materred... but in this game its all just flash bang sparkle and by and large every move is basically the same. and TP is essentially Infinite outside of AOE
sam for example I couldn't even tel you the difference between jinpu and shifu visually and I don't really care either. as long as that buff icon goes up on my buff bar that's all I care about.
Same kinda thing with paladin. savage blade and riot blade if you just showed me the animation I couldn't tell you which one was which there's no substance or weight to either of them... just slightly different flashes and splarkles... blurred in with everyone elses flashes and sparkles. You never get that oomph!! Like "holly hell my jinpu hit for x damage..." because its just a blur in the middle of loads of other blurs....
Regarding a change in direction though I sometimes think the devs often listen to what we say but they don't actually hear it...
Its like the stereo typical husband and wife sat at a dinner table thing. hubby is watching tv and the wife is talking to him about something...
"I tell you jane at work is lazy every day we all have to pick up her slack and yet the bosses never see it.... I don't know how she gets away it all the time"
and the husband is there going " mmhmmm, mhmmm mhmmm,"
then the wife be like " are you even listening to me? what did I just say?"
husband is like oh um " jane is your new boss at work???" because all he heard was "blah blah jane at work blah blah blah boss blah"
or in se's case.
Players: "here's a cool idea for a glamour catalog designed in such a way that wouldn't stress servers and had virtually limitless capacity"
Se hears "blah blah blah Glamour blah blah blah blah more capacity blah blah..."
or with eureka when players spent years saying there'd like structured engame like XI then we basically got an exp party crossed with fates that everyone hates. and has hated since like 2.0...
its amazing how many times they can get things soo wrong.
I do think though that if they were going to look into a change of direction they should do a mass survey thing and not just for current players. but for former ones as well. that would give a better set of results. you might find for example that the 500k current players love the treadmill / tomestone grind which might look great to devs. but it might turn out to be the reason 5 million players quit because they hated it and gear was meaningless.... suddenly it doesn't look so good..
Edit:-
On the topic of coding I don't even know what to say. I look at xi and the fact it's nearly 20 years old and often suffered lolps2 limitations. But they pulled out some real nice stuff with that code and had a living breathing dynamic world that was ever changing.... zones that had mazes that changed every hour. Puzzles and things all over the place. Constantly pushing the limits with various additions like tactics pearls and large scale battles like besieged. Managed to make virtually every new content feel few and fresh....
They could do all of that on code that's nearly 20 years old for heaven's sake. What the he'll is the problem in xiv
