They should do it, to remove Skill Bloat to the most less minimum/ or to make classes more interestign with added new skills to fill the created gaps from making more Skill Chains of obvious ones, where even in the skill descriptions is the read about combinations - where it makes only sense to use those skills, if a certain other one has been used before to be more effective.

Its very disappointing to see, that Skill Combos havent found their way into PvE Gameplay, despite that the mechanics are used already for PvP...
Wasnt it said in one of the letters of Yoshida, that they are doing these skill chains for pvE?? So for me it was even more so disappointing that they seem to have shortly changed their minds on that whyever ... because personally I see absolutely no reason not to implement that system completely into the game for all modes.

How to do that, I will go into details in my suggestion threads for the classes, now that I ve got a good impression on what Shadowbringers has changed all on the classes and combat system...
