I know they've been deemed too inefficient to use for quite some time, and I understand the math behind it.
However, I long for the days of old, where you get into party and after the pleasantries you set up a skillchain and burst pattern. It's one of the things that got me hooked, that cooperative party dynamic which really set FFXI apart when I was beginning.

Unfortunately, unless SC are significantly better than TPburning, we of course will never see such dynamics again.
I haven't seen any other topics discussing possible fixes, so let's start here?

As a start, marginal TP (over the 100/200 mark) should improve the WS either as the difference in TPmod between 100~200~300, or as bonus effect tacked on. This way TP gained waiting on your friend is not "wasted".
Second, WS dmg should perhaps start at double combined WS dmg and go from there, improving w/ higher SC tiers and WS count.
As for MB, I'm not much of a mage, so I'm not sure as to that particular.
