Why doesn't pve have pvp combo structure?

[Goji1639]

So if I see the target is about to disappear (add about to die, boss about to become untargetable, w/e), and know I have 4 GCDs left, I can go 1212...[thing disappears, new target appears]...3 instead of 1231...23 and taking an extra GCD to DoT the target.

Or for War you can do the opposite and break your combo to end on 3 to refresh your buff before downtime.

It's not supah deep, it doesn't make or break your parse to any notable degree, but there are reasons to break your combo. I'm sure I could think up examples for other classes, but I don't play many at a high level lol.

Knowing you have exactly 4GCD's until a mob dies or invulnerability phase starts up is something that will rarely, if ever, happen, but I guess that is one use for breaking combos if you're trying to extreme min/max something.

There's no reason that throwing the basic combo buttons onto different keybinds couldn't still be an option; but 99.99999% of the time I'd still want them consolidated, though.
