If it is not broken, DO NO FIX IT!

The fact is that freedom to make any character you want means, by necessity, the freedom to mess up your character any way you like. Some choices will always be better than others. True balance is impossible, which would not matter if you did not have a community obsessed with being hardcore and min-maxing.

If character A can bring the debuffs you need, do exceptional damage and survive, why would you bring character B who free-formed it, has the debuff, but does less damage because he chose to allocate stat points to boost his self-healing? The ability to choose is golden, but mix-maxing is all about getting what you need and minimizing redundancy. A build that overlaps with the job of another member of your party is sub-optimal in a hardcore environment, and therefore, less desirable.

Long post short: Free-form is not free when some choices are better than others. And since true balance is impossible, there is always a "right" and a "wrong" way to build your character for endgame content.

Well You can't main heal or Dot effectively on any classes but DoM. I think the idea is that you are supposed to be able to be versatile. Ok my grind party lost the Gladiator so now I'm going to tank as my Pugilist instead of DD. I change my actions to what I need for Tanking and on we go. This is better than sitting around waiting for the Gladiator we just invited to run from the node. Or if we couldn't find another Gladiator we could just continue on without them. The same applies to NM hunting.
