Playoffs between e.g. 2nd bottom in one league vs 2nd top in the lower league to decide promotion I regard as fair. There is logic to the system.
Playoffs between e.g. 2nd top in one league vs 4th top(who may be as was said 20 points behind) to decide anything is just plain wrong.
Celtic didn't lose the title just because of a couple of unlucky(for them) breaks - they lost it because they weren't good enough over a whole season. That's the difference.
If playoffs are so great, why not include the table-topping team in them, wow that would be so exciting.
Playoffs - ludicrous...
